I've currently got a 3GS 16gb and obviously fancy the new one. Going by what I can see on the 02 website I can upgrade early for £20 a month for any months outstanding on my current contract. Which equates to £300!!

02 recycle will then give me £228 for my 3GS........ Which means a new iPhone 4 for the princely sum of £72!! Obviously on a new 18 month contract like I'm already on.

This is how I understand it, which seems GREAT to me! Am I missing something? Or does anyone know something I don't?
