I began experiencing issues with my 3GS battery this past Saturday night. I delt with it yesterday (Sunday) but I decided to bring my MacBook Pro with me today and do a restore. Well unfortunately, the battery completely died in the way into work while listening to a podcast on connected to my vehicle charger.
The good folks at the Apple store in the Willow Bend mall set me up for an impromptu appointment, and I walked out of the door some 15 or so minutes later with a new iPhone.
