www.onestopphoneshop.co.uk are offering what seems to be a good deal, I went for it anyway....

It's on Orange with a competitor tariff (Vodafone's) they are offering 11 months free line rental on a 12 plan and it's 22 quid per month.

So your only paying 22 quid for the phone.

The deal is by redemption over the 12 months in 3 stages (seems to be the norm now)

I'm not a heavy user, so I like to look for the deal's that are cheap if not free
