I've had the iphone 1st gen, iphone 3g, and now I have the G1. The G1 is hands down a better phone. I love the keyboard, although at first it felt kind of small. The screen on the iphone is perhaps the only feature that is better than the G1...and that advantage is only marginal. Please don't listen to the iphone fanboys. Try both phones if you can. I'm sure you know someone who has an iphone, and t-mo reps will let you test out the g phone. Tell us what you think!
