I'm currently in the stage of choosing a new phone, but HOTdamn, there's a lot of choices out there.
Right now, I'm rocking an (almost ancient) iPhone 3G, which has seen better days. Yes, I am an Apple fanboy, have been for quite some time, but I have no problems with Android or even the new Windows Mobile OS.
So I'm not asking to start a flamewar about which system is better, just some hints / tips / etc. What phone are you guys using, what would you recommend, why, etc.
