I bought my Nokia X3-00 in April, and I enjoyed it for about a month before it began to be painfully slow. I tried and installed an update on the phone, which for the time being solve the trouble. But then about half a month later it was even slower than it was before. Now, when you reset the phone, just solve the difficulty about a day before slowing down. And turn off the phone and fix the problem for about an hour.
