I've been a blackberry fan for a long time now.
I used to own the iphone, nokia e71 and the imate before - but, none of them could really match up to the Blackberry Curve 8900 I have right now.
I think this could have a lot to do with the fact that the BB has a very good QWERTY key-pad, and the track ball kicks butt.
Just sold my blackberry bold (lovely phone that was). But their lack of an API and SDK for developers that was useful motivated me to switch
Will be picking up the new iPhone 3GS tomorrow probably and will start working on a few apps for it!
Xbox 720 Next Generation Console - Video gamers check it out!
Ha Ha, i was surprised when you listed only the iPhone and the blackberry. I use Samsung's corby pro. It is a fully effective touchscreen device along with a slide out qwerty keypad. It also comes with 3G and Wi-Fi and a motion sensor.
