So we all know about the dreaded "No Data" issue that's been plaguing the Charge, but has anyone else noticed that the phone either doesn't—or just takes very long to—reattain signal after it starts "searching for service"? On countless occasions I've been in a no-service area, and after going back to a strong-signal area I've had to enable and disable airplane mode in order to get service back. It's almost as if the phone just stops trying to find a signal after a while... Is this a battery saving feature normal to the phone, or is it a bug?
