lately ive been having some problems with my 3g connection. the status bar will show 4 or 5 bars along with the 3g symbol but i have no connection. i cant hit the internet or use any of my apps that use a connection. i either get an error or page cant be displayed. as soon as i restart my droid 2 everything works as it should be. i also get all of my emails and notifications once it restarts. any ideas on what could cause this? restarting every time i want to do something is annoying. i do have sync enabled as well.
