I upgraded to the iPhone about six months ago and have loved it. It is amazing to have a phone, tons of music, fast Internet, a quality camera and lots of cool applications on a phone. The applications are probably one of the best features on the iPhone. Last night for example, I was trying to figure out where to grab some grub. I didn't feel like straying too far from East Village, so I used Urban Spoon, locked in East Village and it gave me tons of interesting options. I ended up checking out a sushi place called Taka. Pretty good spot if you're looking for sushi in East Village (however, I still haven't been to Nobu right down by Hard Rock, which I hear is pretty tasty).
The biggest annoyance about the iPhone (other than the fact that it doesn't have a real live GPS like the BlackBerry offers) is that when you download a free application from the iTunes store, it sends you a receipt for $0.00. What's up with that? I understand the sending of a receipt if they charge your account for making an actual purchase, but I think Apple should immediately stop sending these phantom receipts...it crowds up my Gmail account with needless emails. I would drop Steve Jobs an email, but it sounds like he has bigger issues to deal with at the moment...
