I don't have one but what i have seen of them tells me the iPhone is overpriced- you are limited to their choice of a carrier and usualy must buy into a 2 or even 3 year contract. This is on top of the fee to actually buy the thing (got a spare £269 on you for that?). You say you have had no problems with Sony Ericson phones? i would suggest one of them long before one of Apple's new "trendy" phone.
