It's going to be expensive it you try to turn the Blackberry into something it was not designed for. It's a professional-grade communications device and PIM. If you want lots of wow-ee bells and whistles, get an iPhone. If you want a multimedia device or a gaming device, get a PSP. You can personalize your BB for almost nothing, but turning it into something it's not is going to cost, and it will never function like a device that was designed for it's main purpose anyway.
