'''Hi, this is my first quistion here :) I accidantally droped my iphone 3g very hard and the screen poped out a littile...

Already tryd this. And after the restoring or updating finishs it keeps rebooting again. And if you got lucky after 2 hours of rebooting it will start normally for a minute or less then the screen freez for 5 minutes then restarting again and again. Its a hardware problem. Any way I got iphone 4 now and I disassimbled my 3G and donated the enternal parts such as the LCD screen, digitizer, speaker, antenna and the bottons to my frinds :)

some times when you finish the reassembling and you push the screen back to its place. some cables plugs out in the same moment when you push the screen mostly cable no# 1 and 4 so be carefull wile installing the screen.

Am 90% sure that its dead and you need a new digitaizer but ckeck the 3 cabels under the LCD maybe it just unpluged after the drop.

If you are talking about the two big external scrows in the bottom of the iphone betwean the speaker and the mic. these are only for holding the LCD and has nothing to do with circuit, and you can run the device without them. even if the LCD is not fully reassembled you still can run it (but the 3 cables under the LCD must be pluged well).
