Mobile Phone

I have been looking at new phones. My contract expires in January, Orange have already been on the phone trying to get me to take a new contract but their offers were rubbish. My phone broke 2 days after they rang. I have an Orange SPV C600 and the main menu button stopped working. Which means I can't unlock it, nevermind do anything else. So I have gone back to my SPV C500 which is actually a better phone (the keys work anyway).

I have been looking at all the offers from the different companies and I have always avoided Three because their coverage was always rubbish but it now appears they are as good as the others. I then noticed that from next month they are lauching X-Series which is like unlimited broadband for phones and comes with some useful programs like Orb, Slingbox, Yahoo & Google among others. At the moment there is no indication on price, it will be announced on the 1st December. Only 2 phones will be supported initially but I quite like the look of the Nokia N73 after a lot of research, takes good photos and can use my existing 500MB MiniSD card. It may become my new phone on Three if the price is OK and they will transfer my mobile number?
