back in feb, i purchased a nokia 6288 from vodafone. It worked great until a couple of weeks ago, then it just started randomly turning off, and i couldn't turn it on again, if i did manage to get it on, it was only for around 30 seconds, then it would just cut out again. I took it to vodafone and they sent it away under warranty. It came back, i stuck my sim in it and it just cut out again. I took it back again and vodafone just gave me a new handset, i was very pleased!
