I'm not quite sure how it happened but for whatever reason the screen on my 4 month-old N900 died, I am only seeing colored vertical lines on the left side of the screen. If I tried to look more carefully I could barely make out somethings on the screen, like the time when the screen was locked. The device itself appears to be working but useless because I am unable to see anything, so I sent it in for repair. Luckily, I have my old 1st Gen iPhone laying, so I jailbroke and unlocked it, threw my TMobile SIM in it and I'm good to go for now... Definitely missing my N900...
