Just ordered a Samsung Galaxy S II from dialaphone on O2
£29 initial payment
£21.50 for 24 months
I looked at a few smart phones narrowed it down to a couple of phones including the Sony Erricson Arc, Nokia E7, HTC Desire HD, Torch 9800 and the iphone 3GS.
Looking at the technology in these phones - camera, battery, software, reviews and taking into account what I got for £21.50 I thought this was the best deal even for the small initial outlay
