I'm on £35 24 month contract with T-mobile 1200 mins, 500 texts and (allegedly) unlimited data (in practice 1Gb) - phone was free through Carphone Warehouse. Beware though: you will need to upgrade to Web and Walk Plus (which gives you 3Gb total data) to get things like MSN working over mobile internet conection (It works fine over wireless) - If that's important to you have a search there is a thread about it somewhere (Power Search is better than normal search!)
