The only time I ever had problems with handcent was back when I was a newbie and thought task killers were a good thing. I killed EVERYTHING several times a day with my task killer. Then all of my text messages were deleted once. From that point on, I have only used a task killer when my phone lagged badly (maybe once a month), and havent had any problems, especially with handcent. My broswer crashes about every 15 minutes now, but I think thats a kernel issue.
