Hi there, I have had my desire for about 3 weeks now on O2 contract, and have an annoying problem... I appear to lose signal intermittantly, and end up with a little grey 'x' by my bars. However, this then STAYS like this even when I am back in a normal area, sometimes for hours before I have even noticed that reception was lost! The only way that I have found to get reception back is to power off my phone and restart it. I have called o2, and the only advise they had for me was to remove the sim card and 'give it a little wipe', and all will be ok.... Anyone else had this problem???
