iOS 4 (Previously called iPhone OS 4) GM version was released yesterday . A lot of testing has been done and I’ve found no problems with it working. Hopefully in a couple of week the public version of iOS 4 will be released maybe.
If you have any problems with iOS4 and www.unlockit.co.nz please let me know

i had an issue. i had an APN installed when i upgraded from 3.1.2 to 4.0. Everything was installed, i couldn’t find the profiles setting and i wasn’t able to use 3G (i currently use the unlimited ipad 3G data plan in my iphone). i tried to reinstall the APN setting and was given an error message that only 1 profile is able to be installed at a time. However there were no profiles available. after some back and forth, iphone config utility, and restarting several times. 3G started working again with no troubles. There is no record of changing my APN and iphone config utility does not show anything installed.
hello yes umm i have iOS4 GM running on my 3g and i went to ur page to disable data and it work not work it says: safari could not install a profile due to an unknown error.
is there a alternative of installing this if sooo please let me know
Under iOS 4 there is an option in Settings, General, Network called “Cellular Data”, Just turn that off and it disables Cellular Data. Its the Official Way of doing it.
i have the same problem of luckyjason.
Is there a way to remove profiles manually????
I do an “Erase all Contents & Settings” and reinstall iOS4 GM, after JB with redsn0w 0.9.5b5-1 this jb enable multitasking and wallpaper on 3G. @luckyjason
I just installed iOS4 GM on my 3GS, I can’t get any profiles to installs, I get the same error message: “safari could not install a profile due to an unknown error.”
Which profile are you trying to install? Fake APN which you don’t need to (see article about this) or another one? which existing Carrier?
@admin Before I upgraded to iOS 4 GM today, I had successfully used your site to install a blank custom profile (I put “Broadband” in the APN field, everything else blank) to use an iPad microsim with my iphone. Worked like a charm on 3.1.3.
So I’m on iOS 4 GM and trying to install that same custom APN gives me the error: “safari could not install a profile due to an unknown error”. I get that no matter what setting I put in your website.
Any ideas why they can’t load any APN settings? Same baseband, same SIM, different OS.
Did you restore from scratch the iPhone from iTunes 9.2 (Developer only) . and then restore your settings from itunes?
First, thanks for for your help, I really appreciate it.
Yes, I created a custom firmware file with pwnage 3.1.5 (replacing the Cydia and other files specific to iOS 4 GM). Put the phone in restore mode and ran the update restore through iTunes 9.2).
I set the phone up as a new phone, I did not restore settings from a previous iPhone backup.
I would try without trying to jailbreak the iPhone..
Ok i planned on getting a iphone 4 in a couple weeks. Will this process work with the new iphone 4?
As no one has an iPhone 4 to test it on its impossible to say.. but it “should”
I just updated my unlocked 3gs (not jailbroken) to ios4. Tried unlockit which I used successfully prior to the upgrade. After selecting US-ATT and clicking Create Profile, a new web page opens with an icon of a blank document and underneath it says ConfigurationProfile with a size of 9KB. I do not get the screen that should show me the APN Carrier Settings with the Install button. Please advise. Thanks.
After doing settings for apn Change to vodafone de… Safari tells me that Safari is Not able to Change it
same error here
I updated my 3gs from 3.1.3 to ios4, removed the previous APN profile before installing ios4, installed ios4, installed the new APN and it works 100%. I was wondering if it works with iPhone 4, im assuming it does?
It should.. I haven’t got one so I don’t know and no one has let me know otherwise yet..
We’re getting the same “Safari cannot install…” error on a 3G – jailbroken and unlocked, on ios4.
Any ideas of other ways of installing?
And the profile was UK – T-Mobile 🙂
i am having 3g , installed iOS4 from itunes 9.2 and JB , Unlock also, now everything is working accept APN , there is no way i can enter APN setting, please how do i setup APN in JB iOS4 Unlock 3g iphone
Hi there, I bought an iPhone 4 yesterday and activated its SIM in my iPad on AT&T
meaning that it ended up being pre-pay data only.
I was hoping to use this for VOIP and avoid a voice plan (and activation charges) by using the APN changer to change the phones APN setting to match what the SIM is provisioned
for (broadband) but the phone will not take the APN change using the tool.
When I use the tool if rotates the screen (as if it was going to install the
profile) but it never actually does. The phone is iPhone 4 with OS4 (not
jailbroken).
Any ideas anybody?
I still dont get it.
I have a 3gs, had a fake APN, didnt know i had to remove it before I updated. and now that i have updated to iOS4. I cant delete the previous fake APN. Help

Dear
I have 3gs i phone running on firmware 3.1.2. Jailbreak with blackra1n.
Presently I am using the phone as a modem to connect to my laptop. The
tethering was possible with APN changer from your site. Now I am going
to update firmware to 4.0 and dicard jaibreak. Will my Internet
tethering still work or what is the alternative.Pl guide.
Hi, have a 3GS now with jailbroken IOS4 and have cannot install any config file through Safari. Just shows the file name and size but nothing happens (this is true also for certificates for vpn and other settings).
Does anyone know how to fix this?
whatever method you have used to jailbreak it has broken it.. I would try again
Please admin, many people commented with same problem I am about to and you haven’t replied. Also emailed but no response.
I have a 3GS running ios4 an it’s never been jailbroken. Before the update I used fake apn, and before updating I’m pretty sure I removed profile. Since updating, I haven’t been able to use 3G data, and when I try install a custom apn from here it says only one profile at a time allowed: thus the old fake apn is still in system and so far untouchable. Please look into this, I implore you.
Nothing much yet sorry
I had a 3GS with no data so I used unlockit to block data. Just got an iphone 4 and I have a data plan now. After restoring from my 3GS backup, I cannot access data, and I cannot remove the fakeAPN profile. I cannot install a new profile either, as it says there is already a profile installed.
I need to create a fake profile, however, under the Custom APN page, my service company is not listed. I live in Vietnam and use MobiFone. Any ideas for me? Thanks! 🙂
Same problem as #33.
Problem solved. I had the following issue: “I had a 3GS with no data so I used unlockit to block data. Just got an iphone 4 and I have a data plan now. After restoring from my 3GS backup, I cannot access data, and I cannot remove the fakeAPN profile. I cannot install a new profile either, as it says there is already a profile installed.” Like Andrew.
Here is what I did to fix it:
1. Restored Iphone4
2. selected setup as new phone
The outcome was that I now have a functional Iphone 4 with visual voicemail, and 3g data working, and all of my previously installed apps re-installed. I will have to re-sync all of my music, photos and videos, and setup my email accounts again. No biggie though.
To admin- thanks for the excellent work around that allowed me to use my previous iphone worry free, and data plan free. Smart and generous guys like you are much appreciated.
When everyone is saying to do it the “official” way, I think that way just nags. Because everytime I open the message map or safari app or anything that attempts to use a connection, a message will pop up telling me to go to settings and re enable the Internet connection. But with fake apn it doesn’t nag you everytime you open an app.
@Andrew
I´m having the same problem… what should I do? I don´t want to lose all the data I have installed on my phone.
How can I uninstall the APN Profile on Iphone 4 restored ?
I have installed a new profile without any problems and it successfully changed the APN (Checked on My Vodafone Billing). So all apps for data are using new APN. However Internet Tethering is still using office.vodafone APN and not isp.vodafone.ie which is highly billable! Can you tell me how to make the profile also change the Tethering APN?
Many thanks
I installed apn on my phone then updated to ios4 now voicemail won’t work. I tried installing it again and it says can only have one profile. But I don’t have any profiles. What do I do? Please help
@Eduardo
i am having the same problem, didnt remove fake APN from 3GS before updating, i now want to use data but cant, i dont want to do a fresh install because i want to save all my data, folders, messages etc. etc.
Any fix???, i need help!!
Same problem here.. updated without taking away the fake profile, now I’m having a dataplan, but can’t access it because I can’t get rid of the fake APN. Same here, don’t want to start with a NEW install, not only would I have to reorganise everything which is time consuming but not impossible, but most important, I would lose all my text messages, many of which are business related.. so too important to lose!! URGENTLY need to get around this problem!!!

same problem! help me please !
what is the website to use to have my iPhone use go phone Sims for me to get 3g data
Hello all. I had the same issue. Half-way through this thread someone said to use the email option. go through the option of emailing yourself the install with the Broadband profile. use the email account that you have on the Iphone 4 to open the email and the attachment. I used yahoo. The key is that it has to be the account set up on the iphone itself. You CAN’T open your email in Safari and get the attachment to work. (I tried for 3 times)
I hope this helps! Mine is rocking the 3g as I type! Thanks to this website.
I’m going crazy it worked once on my iPhone 4 and now it wont work again I switched it from us at@t to is singular and now it won’t work
Having issues with 4.3.1, Not working
I have an iphone 3GS running iOS 4.3.3. I understand that disabling data in the settings option is the official way, but I’d like to disable data while still allowing picture messages to be received. Disabling data in settings also blocks picture messages.
I could do this on iOS 3 by using Fake APN. Is there any way to accomplish this using your APN service on iOS 4?
This service is wonderful and thank you very much for putting time into creating it for us.
i have the iphone 3gs running 4.3.3 and i cant geet this working… im pulling my hair out i have reset my phone and reinstalled the setting like 40 times.. even tried a new sim card. any ideas?!
