BB Curve :: 3G 9300 Crashes And Reboots Constantly?

However the last few weeks, it's been cutting out, Crashing, freezes up. Boots up, goes to the White Screen and goe's black, doesn't come on for at least 5 minutes before it boots up.I've been trying to reload its software but unable to because the phone freezes up and cuts off. So i have no clue what to do at this point. It has little episodes where it spazzes out goes white and the screen flickers for 20 seconds and shuts off. Battery pulls have been tried to fix the issue but even that isn't even working.i'm a Blackberry Guru myself but i've never seen this issue ever before on my Curve 3G. The odd occasional crash maybe due to over load on the memory, but this is getting beyond a joke, i can't even boot it up for at least 10 minutes or even a minute after it boots up it goes like Hell is decending into the thing.

UPDATE: I'm also being informed i'm not the only one with this issue, a fair few blackberries have gone insane in my area. Like if a hacker is tapping into the software and destroying it inside out with a virus or something. < An idea but not accurate.
