This is really strange and I'm not sure where to go with this.  My wife's 8130 has a plain white screen, no icon, no nothing.  She turned it on yesterday morning and nothing came up but this white screen.  We tried battery pulls with no changes.  It does, however, vibrate when she gets a call or a text.  The LED lights up as well.  So, she can't call out since she can't see who she's calling, but she can recieve calls.  Is this typically a software or hardware issue?  Would something like this be covered under warranty?  Has anyone else had this problem?  To me it would sound like a broken screen if it was black and not white...so there's where I am confused.  Anyone have any suggestions?
