is this teh sort of sale you are looking at
APPLE IPHONE 3GS 16GB BLACK LEGAL FACTORY UNLOCKED = UK on eBay (end time 10-Apr-10 04:17:12 BST)
i like how he says his phones are legaly unlocked pmsl
its not illigal to jailbreak your phone
on a side note and i know i have already mentioned this but if you do buy an iphone you will never be able to send photos,ringtones etc or recieve them from your friends as on teh iphone the only thing the bluetooth allows is connection to your headset.You wont believe how much you miss been able to do it until the option is gone.
ps:
again be very carefull with ebay because most of these people with ebay shops are operating from their bedroom and even if you pay through paypal dont assume you have any protection what so ever.My friend ordered two laptops and only one was delivered and despite exploring every option available paypal still ruled in the dodgy sellers favour and he is now out of pocket over £300
IF you know a student get them to purchase the phone from apple becaus ethey give discounts on apple products although im not sure if this includes tehir phones
