Re: My 9810 is att's,but no 2G mode
It's that way because AT&T's approved settings dropped allowing manual switching to 2G at some point. When you install an OS from another carrier, if you leave the vendor files in place, that carrier's settings are put on the phone. That can make the phone horrible to use on your own carrier. When you remove the vendor files, then your own carrier's setting to take effect. There's no third option to choose your own. The manual 2G switching is one we'd all like back on AT&T, but they're phasing 2G out. So, no option to manually switch. But, if the 3G signal is too weak, your phone is supposed to automatically switch to 2G.
