Had to send my phone back to O2 as it wasn't charging properly, as if there was a loose connection with the charging point at the top. So I got a delivery today which I was expecting to be my repaired phone. Had a note inside saying that as they were unable to repair the phone within 7 days they have replaced my phone.
So when I open the box, inside is a brand new Xperia Arc.....just setting it up at moment but it's all looking good so far!
First time I can say thanks O2
