Bit of background, I had a Desire for two years and never had any problems, but lost it two weeks ago. Was due an upgrade anyway so got myself a Galaxy S2, but somehow managed to lose that too. 
So anyway, i'm now back using an old Desire my friend had.
It was in pretty good condition, but he had it rooted a while back and since then the wifi keeps turning itself off and on randomly every few minutes. Also, every now and again when trying to unlock the phone the touch screen becomes unresponsive and it won't let me swipe down.
We thought this might be a software problem, so I unrooted the phone and have it running on gingerbread again, but this hasn't stopped the problem. Anyone have any ideas? Any help would be greatly appreciated as I'm a bit of a technophobe!
