Over at
www.e2save.com on T Mobile, subsidised via cashback.
Bear in mind that the 6230 is a valuable phone, worth £100 or so 2nd hand, and with 200mins xnet to boot, this deal is a stonker!

Also, E2save are a subsidiary of Carphone Warehouse, so no shady fly-by-night outfit.
I have an affiliate link, which I use to raise money for a charity a friend
of mine works for. It's called Amy's Retreat, and it cares for kids with
cancer - I raised nearly £130 with the 7600 deal, and am hoping to raise a
bit more here.
Here's the link...

I've a letter from Amy's Retreat thanking AVforums bods for the cash raised over Christmas with the 7600 promotion - I'll get that scanned and uploaded when I get a moment.
Happy Easter y'all!
