Hello, Rather than use the network that the 3G iPhone is required to use in the UK, o2, I went ahead and bought a Revolution 3G unlocking SIM for my iPhone. It worked okay-ish, in that it would take a long time to acquire service but otherwise worked fine. My first question is, even though my non-o2 sim is 3G capable, why can't I get 3G? UPDATE: Got my service back. Re-inserted the SIM a few times and left it for a few minutes.
