In the UK, had my O2 iPhone officially unlocked by them. iTunes showed the message 'congratulations your iPhone is unlocked' so it went through ok. When I first had the phone unlocked I ported my number over to Vodafone. Everything works great - but looking at the online billing I found a charge for an MMS sent to '1010'. I recognised this as the O2 MMS number used to set up a new phone with picture messaging. Now I don't really use MMS so I just disabled it to prevent further messages being sent. Recently, I updated the iPhone firmware to 3.1.3 with a clean install. All my settings were lost so MMS was back on by default. Predictably, another message was sent from my number to '1010'. I was of course charged for it. This is really starting to get on my nerves. It is a legally unlocked iPhone and yet here it is sending messages by itself. Any tips?
