I've been having issues with my 925 as of late. It will randomly loose service in an area that normally has great service, so I know it isn't just a weak area. In order to get service back I have to reboot the phone. This occurs at least once a day. I'm on GDR3 now, but the problem still occured on Amber/GDR2, so I know it can't be OS related. Has anyone had this issue before?
