I dropped my Sony Ericsson C510 by accident. The back cover came off and the battery came out. I put the battery back in and switched the phone on again, but the screen only displayed half black / half white and some lines down the middle. I can still receive calls and sometimes the phone buzzes as though I'm receiving a message (I can't tell if I am or not because I can't see anything on the screen). The lights on the keys also light up if I press a key. I tried connecting my phone to the computer to see if I could get some pictures / music off the phone, but a dialog box popped up and said it coulnd't install the device software because no driver was found.

Does anyone know what might be broken on my phone? And how much / how long it would take to fix? Will I be able to retrieve the pictures from my phone? There are some sentimental pictures of me and my boyfriend on holiday that I'd like to save if possible.

Any help much appreciated!
