Developing for the Samsung Uproar M100 Cell/MP3 Phone?

Michael Buffington asks: "I just picked up a Samsung Uproar cell phone combination MP3 player for a much reduced price of $179.00, which is a great deal when you consider what a nice digital mobile phone costs these days combined with the cost of even the worst MP3 player. I'm impressed with the phone and it's features, but would like know if any other owners of the phone have thought of the feasibility of developing software to interface the phone (other than the MusicMatch bloat-ware that's required on an Windows machine no less). I'm considering diving into USB driver programming, but before I do, I thought I'd Ask Slashdot to see if anyone has already figured out what's possible? It has 64MB of RAM, perhaps it could support a custom OS? Maybe rather than just being able to download MP3's, I could download phone numbers and appointments into the phone. Would be great to find out what the limitations are." That's a great price for such a combo and it would be an utter steal if this device can be extended beyond the limits of its existing software. Anyone else playing around with these and would care to share their thoughts and experiences on this device?
