Well, true to form, T-Mobile have been very good about it. Rang em up and told em I didn't like it, and they sent me a pre-paid Special Delivery bag with a returns note in it, and once they recieve it back they said they will reset my account to how it was, and I will be eligeable for a new upgrade, and could even have the £10 per month discount I was initially offered - which I'll probably do and stick with my N73 as I can't find a phone I want other than the iPhone 3G and I cna't justify paying out hundreds for one of them!
