Hello,
If I upgrade my 60GB data allowance to 'unlimited' will I have to start a new 12 month contract?  I thought I read somewhere that the period remaining on my existing contract wouldn't be affected but I can't seem to find the page anymore.
Thanks.

Unless you opt for the no-contract option, which costs £2.50 per month more, you will start a new 12 month contract.
Details in the FAQ here I’m already part way through an annual/18 month contract, can I still upgrade??
Take care if you are currently paying a promotional offer price, that would be lost if you upgrade (next question in the FAQ).

Okay, thanks for the info.  Not sure where I got the idea it wouldn't be affected from!
