Specifically, I want to change the internet sharing APN (the one that iPhone uses for Personal Hotspot). Some carriers allow you to edit APNs but mine does not. Is there a way to do this (install custom carrier settings) w/o jailbreaking?

Everyone keeps pointing this website out to me, but it doesn't change the APN for tethering, only the APN used for on device data.
And I just went to that link, and even though I have an unlocked iPhone 4S, I have no option in Settings -> general -> Network (as that site shows) to alter the APN settings at all. It's not a jailbroken phone, so maybe that's why, but the only options I have in Network is Cellular Data, Data Roaming, Personal Hotspot, VPN and WiFi and that's it. No place there to alter APN settings at all. And I have my Network Selection set to manual (Automatic is turned off and I manually select my carrier) and still, no APN settings where that site said it should be. I even opened up the manual for iOS 5 and hit the search button to look for APN and it didn't find anything in the iBook manual, so maybe there isn't a way to do it without jailbreaking.
Correct - iPhones use a completely separate APN for tethering than on-device data. In the example given earlier in this thread, it means that AT&T can theoretically be sure that those who tether will pay extra for the feature. Personally, I use a carrier that seems to permit hotspotting (I've never been billed for hotspot usage) but to be safe I'd like to use the same APN as is used for on-device data. It seems that the only solution would be to install a custom carrier bundle, which I believe is impossible unless you're jailbroken. If anyone has any addl. info let me know.
