I bought a couple of tabs online from USA which were not coming on. After they arrived and I hot them to turn on, I realised some have PIN locks and some like the Blackberry simply no longer had an operating system to function with.

I'm wondering how I can convert these items back to money, which was the reason for buying them. Is there a way to unlock these cheap tabs or give the Blackberry Playbook another lease on life? I've learnt my lesson and am not buying such again, but my money is still tied to these ones, plus other Macbooks and other stuff.

I should have just stuck with my camera business
