Sharp 903

Hi, its coming to that time again of getting a new phone.

Im very keen on the sharp 903. ive heard its on the money as far as phones go. interface is a little more basic than what im used to but it ticks all the right boxes apart from the box that says stick with 02.

I can only find it avaliable on Vodaphone and they aren't an option in the provider stakes.

a) Is the phone as amazing as i think it is?
b)Is it avaliable via another provider.
