Hi, i am using a company line (Celcom) but i would like to get an iphone 3gs. Can someone advise me on the following:-

a) if i sign up with Digi (my wife's no.) to get the iPhone, can i use my Celcom Simcard and is there any issues?

b) what about the configuration, cause i know nothing about special configuration for Celcom on the iphone

c) there is a RM20 difference (monthly installment) on the Digi88 value between the 16GB and the 32GB. can someone give me some tips here? 16 or 32?

Any other issues that i need to know. I use my E71 extensively to retrieve google mail as well as to surf the net, but it it so slow and so small, that's why i am thinking of iPhone. oh, and i hate blackberry.
