So I have the Cingular 2125 and I absolutely love it. It does have some quirks every once in a while though. One of the quirks happened today. My phone was in Flight Mode for some unknown reason. I'm reasonably sure I didn't do anything to cause it. Flight Mode means you have no ability to use the phone as a phone because it is not connected to the network. I Googled for a solution and found out there is a rather obscure way to solve this. Hit the power button quickly and release quickly and this will bring up a menu called “Quick List.” You should see an entry that says “Flight mode” or “Flight mode off.” In my case it said “Flight mode” even though it should have said “Flight mode off” since Flight mode was apparently on. Nevertheless I clicked on “Flight mode” then went back to the quick list menu and it said “Flight mode off.” I clicked on “Flight mode off” and this solved the issue.
