I just came across a BB for $30 at a yard sale. I really didn't need it, but it was a shame to just let it sit there. It's pretty much scratched all to hell, not to mention the screen hourglasses when I turn it on, then says "JVM Error 102".
Is this a problem that can be fixed (I'd love to give it as a first phone to my 12 yr old to see if he's responsible enough for a better one later)?

JVM Error 102 can usually be fixed. Use the method below:

Keep in mind that the Nextel phone will ONLY work on Nextel.

Thanks for the info.
Yes, I know, but I plan to put in a Boost mobile sim card (since everyone around his age here has a Boost phone). I'm not to particular about the BB part. It was just a cheap, but decent 1st phone for him. Boost quit making their throw-away phones, so this one will suffice.
Besides, I can now hold my head high and say I'm the proud owner or 2 BB's.

Actually, a JVM 102 usually indicates a hardware fault. You *may* be able to reload the OS, but don't be surprised if you can't.
