I only got my X10 just over a week ago and the menu, home and back buttons on the bottom were randomly not working and it's only becoming more and more consistant. It's driving me nuts and it's especially frustrating since it's a brand new phone. I can't find anything on the internet and yes my phone software is upgraded. The guy at Rogers was like oh welllll guess you'll just have to wait 2 weeks until the next upgrade then MAYBE it will work again.. Any suggestions?
