New, first post etc.
Anyway I've just ordered a SIM (hurrah!), and I'll be coming from a Vodaphone handset, but I'm not sure whether I need to unlock it or not. How can I not be sure you may ask?
Well because (a) I'm mostly clueless about such things, but also (b) in the past I've put a friends o2 sim card into my phone ( A Sony Ericsson G502, fact fans) and it appeared to pick up the network, and download WAP settings etc just fine. So am I safe to assume my phone is already unlocked, or was that some sort of magic fluke?
