Well after having a very good time with the iPhone I ran into problems today. I was travelling overseas and it had been working just fine. Then when I turned it on, it went into recovery mode. It couldn’t be recognised by iTunes because the “information required for activation” could not be found and it indicated a SIM card problem. Tried a forced restore and the same deal. Rang Optus and my account was in order. Problem is, I faced a long flight home from London without the ability to access anything on the iPhone — no music, videos or games. Have no idea why and sadly the only option is to bring it in to an Optus store. This is a big pain. Once a solution is found, I’ll update this post.
[Update: Well it turns out that it is a known and insolvable problem. The phone is going back to Apple and I am getting a new one.]
