Thanks for the responses guys, it's helped me take a few steps towards the goal
However, I'd like to ask another question regarding the baseband, and yes, I HAVE read over tonyp's brilliant thread about it, but I'd like to clear something up.
My Optimus 2x was parallel imported, but I have no idea what country it was imported from. Tonyp says in his FAQ that he doesn't think it matters what country's stock ROM firmware and BB you install, so can I truly install any country's firmware, and then use the GetRIL app? It's not like I must install firmware from the country closest to mine (New Zealand) or anything right?
Thanks in advance.
