Nothing technically wrong with the phone. If it did what it was supposed to then I'd have no issues. What are these 'so many' problems you speak of?
* I've complained about text/contact lag like everyone else.
* I've lost about a dozen emails because this thing can't decide weather it is connected to the net as described on MacRumours as a BUG.
* I've complained about a crap signal in areas like London.
Oh wow, 3 problems in which almost everyone has complained about. If I've got a dodgy phone, then by your words so does everyone else. I use this phone to keep in touch with suppliers and I am losing business and work time because of it. This iTunes issue is just like text lag that people said they 'weren't getting' - and then it suddenly hit them.
I agree with the buggie phone
But why on earth are you still using it if its costing you time and business?
