No problem - we're all customers here (bar a few o2 employees) and happy to help. If it isn't too much too ask, could you update us on how you get on. I'm sure your experiences will help others.
BTW, o2 may not accept the phone back now its a couple of months into the contract but a phone call to discuss with them will help. First though, you'd need to follow the process and go through the receiver who should advise you on the next steps.
