Okay, I've got an iPhone 3G on Pay as you go. And I wanted to know how to upgrade to 3GS.
I've heard I'll have to basically just but the 3GS as a separate purchase, and then put my 3G Sim into it for all my stuff.
Anyone on here have any advice ?
Do they do trade ins ?
Should I sell my 3G & Use the cash to buy the 3GS. Because It's really gonna be a waste to buy the 3GS Seperately and then
have a £300-something iPhone 3G lying about the house not being used. Can anyone who's been in the situation give me advice on what to do ?
