iPhone 4S Battery Life - Turn Off 3G (Solution)
Hi everyone,
If you want it, you can do it. Don't discuss anymore.
Call your carrier (AT&T, Verizon etc.) ask them "Please turn off my 3G."
That's it! I did it and I'm happy right now.
By the way, I'm from Turkey and I use Avea (carrier).
iPhone 4S, iOS 5
