I have no reception issues (at home or work or anywhere), and it's just functioning fantastically! I LOVE IT SO MUCH!!! I've been playing with it all day and not doing any work Luckily it's Friday I really am in love with the phone. The display is GORGEOUS, and I just can't stop touching it! I had an hour long phone convo on it last night, didn't charge it all night, been using it basically non stop all day today and it's still at 60% battery! I've got 2 push email accounts going, AIM, had music playing, browsing on it a lot, played a bunch of games (mainly the iOS4 upgraded ones to check 'em out), and it's wonderful!! The only thing I wish would happen sooner is that app developers would update their games for the retina display. It's annoying to see some fugly icons next to icons looking so dapper and sharp. But I know that'll just take time. Anywho, YAY iPhone 4!!
