Just picked up an insurance replacement 4S from Bond & Bond, so it's brand new, boxed, with full warranty
I figure I'm probably going to upgrade to iPhone 5 later in the year anyway, so may take this chance to a) Make it a cheaper upgrade later on, and b) Try out an android phone.
I haven't been tempted to open it at the moment anyway while the new jailbreak is yet to be released
Try me out with reasonable offers/swaps.. I'll be taking in to account the current market values,.. so for example, I'd want an extra 400ish if swapping with a second hand S2 (going price ~500?)
Galaxy Note swaps will have me interested. I would consider taking an iPhone 4 but that would be a pretty expensive upgrade for someone
