I don't know if O2 UK have ever carried an Android phone but I'm sure there's a number of iPhone owners coming to the end or their contracts who might upgrade to Android soon and stay with O2. Either that or Android owners on other networks looking to move to O2 at the end of their contract. Me? I've had a dumbphone on O2 for the last two years and been very pleased with them. Just pre-ordered an unlocked HTC Desire and thought I'd try O2 for a few months on a 30 day contract to see if their 3G data side of things is up to scratch in and around London, Birmingham, Manchester and the bits in between. If it's not good then I'll probably be off to Vodafone. Anyone had a positive experience with Android on O2?
