I got my first iPhone on Sat.  – had to have it replaced on Sunday because it would not charge.  Yesterday - the newest phone would not respond to touch and today it started giving me a white screen with vertical lines running on it.  I had to hold down the power button for about 5 minutes to get it to turn off.  It came back up – but would not respond correctly to the touch.  It did what it wanted to do.  Now it just acts eratic and freezes.  I have only downloaded the google sync as an app and it has not been dropped.  I have also done a hard reset on it.  I’m ready to turn it back in and just a newer Blackberry.
