I think i'll take it apart and see if it's just a loose ribbon connector, but it's not the end of the world. It's not the kind of phone i'd miss for a fortnight!
To be honest if it requires anything more than half an hour to bodge, it's not worth the effort. It's a Samsung U800 btw. It's pretty knackered too, the d-pad plastic cover fell off a while ago and i keep meaning to superglue it back on.
@Andy - This was a Samsung phone, not a Desire. I don't use Gmail and for some reason my SIM card wouldn't let me store that many contacts on it. I've got around 100 stored (and now recovered) from the phone in Samsung's "rich" format (stores extra stuff beyond the SIM specification). I'd also quite like to get the few hundred odd text messages off the phone because I tend to store all my correspondences in case I need to look up something later. Samsung makes backup software that works remarkably well which i've now used.
