Does anyone else run into the same problem as I do? If my phone dies or I do a reboot I get to the lock screen and it says no signal and does not pick up a cell signal at all. During normal use it said no signal before, but a few seconds later it got a signal. Now it will not get a signal at all and the only way to get a signal again is to do a factory reset. Is the jump to 2.1 supposed to fix all this too??
