I'm looking to change to 3, and I'm going to go with Talk and Text 600 on a 12 month contract.
The best deal I've been able to find is with go3online.co.uk with a term cost of £180 - http://www.go3online.co.uk/viewhandset.asp?network=THR&phone=6680&payg=N&upgrades=
Can anyone manage any better? My girlfriend will be getting a phone at the same time as me. Do you think we could push for a slightly better deal as a pair?
