So.. im having the same problem.. my trackpad isnt scrolling at all. and it was just all of a sudden. it happened last week, i was using it that morning, left for a few moments, came back and it wouldnt work. i took out the battery a couple times for about 2 minutes, just turned it off a couple times, and it was a hit and miss with those, whether it would work or not.. so i called my provider (AT&T) and since my warranty is up, they wont do anything, but the guy was nice and told me i should think about replacing the trackpad. so i did so. i bought a new trackpad, got a video online about how to take apart my phone, carfully did so, and it worked for a day, and boom, $25 later and its still not working. is there something im missing..? or is my phone dead?
