This deal won't suit everyone but personally I don't mind a 2 year contract. I've currently got 2 phone contracts with Mobiles.co.uk and haven't had any problems with my cash back claims. You submit online bills and get your cheque about 6 weeks later, sometimes sooner.
After cash back and Quidco this deal works out at £13.54 a month.
My wife has this phone and it's excellent with the benefit of wi-fi. You can also chat to anyone else who has a Blackberry through BB messenger. I've recently posted a deal direct through Orange that works out at £15.00 a month after Quidco but that deal only included 300 minutes.http://www.hotukdeals.com/item/605287/blackberry-curve-8520-direct-from-o?p=7787767#post7787767
