Long story short.......iPhone4.....a virgin install of 4.1 did not fix my proximity sensor issue, my "Apple approved" bumper scratched my antenna, and my sleep/wake button was very hard to push and near inoperable.
I made an appointment with at the local Apple store this morning. I walked in and told the genius what the problem was. 5min later I'm walking out with a new phone.
Now that's customer service!
