Best phone for pictures would be the Sony Ericsson that has the 12 (i think it's 12) megapixel camera.
Best for internet is iPhone (and it's ruddy fab in general but camera isn't great)
Think that Nokia is pretty good, but I wouldn't personally trust Samsungs - never had a good one yet!!
Best thing to do is type the model into google and then pop review after it and you should get something that will tell you what they are all best at and what they are bad at!!!
yer I wanted sony ericson but not on upgrade list :-( I know what you are saying about samsungs both my slide phones broke but hoping because these arent slide may be different.
My friend had the Samsung that is the touch screen one (sorry I don't know the model) and she absolutely hated it!!
It's so hard now with the length of contracts as you are stuck with a phone for ages!! They do normally have a 10-14 day return thing though if you don't like it!!
