Anyone else having the problem with 3G disconnected and not reconnecting unless you reboot the phone? It seems to happen about 1/4th of the time whenever I go through an area with no signal. The only way to get it to come back is to reboot the phone. Sometimes you can put it into airplane mode to get it back but usually airplane mode will lock up the phone causing a reboot anyway. I've only encountered this issue with the new radio/froyo update.
