If you really want to get into the settings that won't crash, under the shortcut menu go to the C2G something or other, another hidden menu, but w/ every programming feature/setting available. That portion you screenshotted, won't make it a one click to go to another carrier though, the phones these days are so universally written that they only change small parts of phones and rename them carrier to carrier....I was a bit suprised to see that myself when i found it, but it was always there on other phones as far as Frequency, that's just putting it into actual carrier terms and then breaking it down either CDMA, evdo, gsm, etc. BTW the other hidden menu, blue icon..(fogot name, have to go look at my phone later), is where any setting can be changed, vocoders, speeds, preferred networks, settings i dont even know of, and more. Be extremely cautious if you do explore. ..{I did post somewhere , i think androidforums, w/ a picture guide to show the menu im speaking of}, if you want to search for it.
