The BlackBerry Curve 8310 is a classic smartphone that has been around for a while, yet people still use it to this day due to its functionality and solid structure. Unfortunately, the operating system is rather dated, so when it freezes due to many processes going on, the best thing to do is to remove the battery for a hard reset. Then place the battery of the Blackberry back in and boot the phone up again. This should result in much smoother operation of your phone without having to deal with all the freezing. Unfortunately, this is just a temporary fix.
