You may very well need a digitizer as well. When I dropped my N900 in a toolbox and cracked the display, the digitizer went as well. It didn't appear to have any damage, but it wouldn't work at all - period. Also, pay attention to the images and description if you're going to ebay an LCD. You want the MP2.0 version if at all possible. I know for fact of one distributor that carries the proper screens AND digitizers, and offers shipping options such as fedex 2-day. You won't find that with ebay, where most of them are shipped via EMS or worse from Hong Kong. In an effort to avoid being accused of advertisement, if you'd like the link for the distributor that I swear by, send me a message. The replacement process is fairly straightforward, I've done it twice. If you run into any issues let me know.
