I'm a fan of $AAPL rumors. Here's one that says that Apple will release a new iPhone in September. It will have a faster chip and a better camera.
So... I'm really waiting for faster data more than a faster iPhone. But still, I do have an Apple gift card burning a hole in my wallet.
I've also been very impressed with the recent Android phones. I think what's winning me over is the bigger real estate - ie, more screen.
