Sometimes due to various reasons you may get error messages when you are installing APN Settings (from here or other websites). The errors may include the ones below.
“Only one APN configuration can be installed at a time”
“Cannot Install Profile. Safari could not install a profile due to an unknown error”
Normally these errors may be fixed by uninstalling previous APN Settings Profile from Settings->General->Profiles.
If this doesn’t work a full restore and then installing the APN Settings again (before you sync with itunes)

Hi,
I have iPHONE 3GS. I do not know how to set-up multiple profiles for data networks (APN). As I keep travelling and switching my SIM between many networks, I want to have multiple profiles set-up. How to do it? Thanks for your help.
You cannot.. You have to have 1 APN settings only in the iPhone and either change it by hand or get onto the wireless network and do it that way
hi, i’ve error “Only one APN configuration can be installed at a time”
i’ve reset ALL and resync with itunes but i always have the above error.
i’ve Vodafone Italy carrier but i must change APN for use a promotional pack. The official APN is very expensive 🙁
Hi,
i tried the restore and before the syncing and loading from backup it works. once i put the backup it doesnt work anymore and it doesnt let me reinstall it. it still says “Profile Failed to Install – Only one APN configuration can be installed at a time.” I need the backup on my phone. is there another way to fix this?
But how can you change it, when u have nothing installed and it tells u cannot install a new one?
i keep getting “Cannot Install Profile. Safari could not install a profile due to an unknown error”, it worked on 3.1.2, i removed profiles, restored to os 4, and i keep getting that error, i restored multiple times, not sure what’s wrong ;'[
same that Charlie
I too am getting the “Cannot Install Profile. Safari could not install a profile due to an unknown error” message. I did a clean install of iOS 4 using Pwnage Tool so there should be no previous APN profile. The is no Settings->General->Profiles option for me. I did do a reset of all network settings, but that did not help. Anyone have any ideas?
I have an iphone 3g with iOS 4.0. I JB using redsn0w .9.5b5-4 i keep getting the following error: cannot install profile, safari could not install a profile due to an unknown error.
I did a clean restore and did NOT restore the backup. I still get the same error. I see other people have gotten it to work, any ideas?
I have a 3GS in the US and can successfully install the ATT profile, however once I do I get no option for Tethering in the Network Settings any more. I have itunes on the machine and have updated it to the latest 9.2.0.61.
Any ideas. I previously had this working with 3.x OS. I have removed and reinstalled the profiles several times with no luck.
Any help would be much appreciated.
Thanks

Just out of curiosity, did you upgrade to full iOS 4 before attempting any jailbreak? Did you try installing the new APN settings before or after jailbreaking?

PLz someone help me
i upgraded to ios 4 and didn’t see this until now. i don’t have an old backup (yes i know) so going back is not really an option. that being said i’m getting the error “safari could not install a profile due to an unknown error”
so obviously i can’t change my profile but i was browsing and found a website that was able to install a custom profile into my settings, BUT it wasn’t any settings i needed. what i was wondering if there would be any way to change THOSE settings since it did install a custom profile (it was an ATT tethering profile using cingular network i believe)
Well, I seem to have solved my problem. I took a chance and did a fresh restore of my iPhone 3G using Apple’s official upgrade path (i.e., not using Pwnage Tool). After activating with iTunes I checked the system settings and found 2 profiles installed! I have done a bit of dabbling in iPhone programming and had installed profiles relating to that, but I did not realize that they were automatically reinstalled when I activated a freshly restored iPhone. These did not show up when I did the restore using Pwnage Tool. But maybe they were there but hidden? Anyway, I removed them and then used unlockit.co.nz to install the APN change. Now I have data again on my pre-paid iPhone 3G!. I then used redsn0w to jailbreak my iPhone 3G which was running the full iOS 4.0. Redsn0w gave me the option of enabling multitasking. I just tested that and it works! I tested using Pandora which now keeps streaming even after go back to the home screen!
Thanks a lot guys…
I am on O2 UK- simplicity tariff, on unlocked iPhone 3G. after upgrading to iOS 4.0 there was no data connection (3G/ EDGE)… wifi worked fine though..
Did a clean restore but that did not help as the option to change APN manually was not visible anymore after the upgrade..
Installed APN profile from unlockit.nz and everything works perfect again 🙂
I have a 2G with ATT in the USA. It worked fine until I upgraded to 4.0, now everything works as long I as I am on WIFI, but if I turn off WIFI, I have no data connection. I tried to use the APN changer off of this site, when I select install, a pop up says “Profile failed to install, only one APN configuration can be installed at a time”, I read somewhere it said to delete the profiles, so I went to Settings……General…. and there is no option to select PROFILES, I assume it is because I dont have any installed? What now? I went on ITUNES and tried to restore my phone, it worked, then I went on this site and it let me change the APN, it let me install, but as soon as I downloaded my back up, its back to the same errors. Is there any way to fix this?

3)Sync to ITunes.
4)Jailbreak usning Pwange Tool
5)Sync using ITunes.
That’t it.
Com on? There must be another way?!
Nothing posted above works for me on iPhone 4S and iOS 5.0.1. There is no profile tab at all in settings but I can’t upload a new profile because it tells me there is already one installed.

Hi Graham, I know this is a long time ago – but i have exactly the same problem with my unlocked iPhone 4 and H2O wireless, wich is a at&t carrier. Did you find a solution?
Many thanks!
