A friend of mine very kindly gave me his 2G iPhone about a week ago and I'm slowing requisitioning the phone bit by bit. I now have the phone working with my o2 Simplicity 25 sim (I recommend this to anyone in the same position cos o2 allows you to and its £5 off this month, so at £20/month its the cheapest way to get free data). I decided to try out the app store today but despite signing in to my account on my iTunes which is now tied to the phone, and resyncing umpteen times, the phone still registers my friend's account. Please help. What else could I be doing wrong? The Apple support pages say signing in and resyncing is all it takes. I'm using iphone 2.0 and iTunes 7.7.1.
