It’s slow news Sunday and I’m on the road, so we don’t have much for you. However, while perusing the iPhone App Store this AM I noticed All Things Digital is an Apple Staff Favorite. Hm, wonder which one? And last night, while blowing time in an AT&T Store, I was mildly amused by the truth-in-advertising iPhone 4 display unit trumpeting “No Service.” Indeed, buyer beware.
