I'm trying to use amAze GPS & Phase10 (a game) on my 8310, but I can't get them to work since I've got a "Communication Problem". I just got the phone this week. I don't know if this means anything, but it also says "Unknown Number" at the dialing screen where my phone number should be. Do I need to change some setting to get these to work? I apologize if I haven't given enough info - I'm new to this
