Hey, my trusty Samsung D600's screen has decided to die on me after 2 years of faithful service, I've phoned O2 wh have said I can upgrade from the 11th August (this Saturday). So far on the website, two phones have stood out to me, the Samsung U600 and Sony Ericsson K810i. They both seem quite similar and I was just wondering which in other peoples views is the better option. I think I prefer the looks of the K810i as the U600 does look a bit odd and touch sensitive buttons I have been lead to believe are the work of the devil, any advice?
