i have a curve 8330 and had it for over a year now. the trackball was fine up until the year mark and i went to a sprint store and got the trackball replaced. it worked fine for about 2 weeks and i had to go get it replaced again. the same thing happened so since then i got it replaced 3 times now within a month and a half time period. i dont know if they giving me crappy trackballs or what but now currently i need another trackball. this is getting really frustrating and i no longer want a blackberry with a trackball. do you think sprint will give me a replacement phone since im having this problem so much? i dont think they no longer make the 8330 so will i get a newer blackberry if i can get a replacement?
