Despite what they say, mobile phone cameras are not up to too much. Great for the pub, or quick funny snaps, but not too good for prints, and forget about enlargements of any quality. Most if not all of them also don't have a flash which is a big flaw in my book.
For example, Nokia 6230i has a 1.3 megapixel camera, which is quite good, but nowhere near as good as the 3 megapixel plus flash (plus zoom?) camera you mentioned.
... But then you can't make phone calls through a camera!
