I have an 8GB 3G iPhone which I MAY have to downgrade as I am frantically saving up money for a house deposit!
I'm initially wanting to get a sub £50 phone whilst trading my iPhone - so for example, a sub £50 phone plus cash for the iPhone.
The iPhone itself was bought in September 08, comes boxed complete with all of the original/standard accessories and is in ABSOLUTE MINT condition. I bought a SwitchEasy iPhone case 2 days after I bought the phone and it hasn't come out of it since :)
The phone to replace it would have to have Bluetooth, 3G, WiFi (not a must), push email, unlocked or on o2 and of a reasonable condition (with box, accessories, etc)
I've valued my phone at what I deem to be a reasonable price, but am obviously looking at the trade + cash option as a priority. Please offer away!!
