I just got a blackberry 7290 and when i put my SIM card in it turns on fine. Then after playing around with it for like 5 minutes it turns off and displays Device Error 144, then i hit restart, and then device error 345 comes up. And so on. I've gotten about 5 different device errors. Is there any way to fix this? or put all new software on the phone?

I have been searching this error and the two other people I found on the Internet who had this same issue had to replace their phones, it seems:
