I originally got my iphone delivered to my house on June 24th. I immediately noticed the reception was really bad, much worse than my 3gs. My phone fell off of lap onto the ground on June 27th (Sunday), and shattered the backside of the phone. I went to the apple store at West County mall in St. Louis the next day (Monday),I somehow got really lucky and he took my info and told me they'd be getting more phones in the next couple of days, and that he'd give me a new phone. I just returned from the mall...July 1, (Thursday), and noticed a DRASTIC change in reception. I have held it every way imaginable, covering it with both hands, one hand, in closets, under tables, you name it, FULL BARS AT ALL TIMES. Not sure how, but it seems something has changed in the second batch of iphones. Let me know what you all think.
