I don't think so.
Edit: This is why:
You'd need to plug it into a computer (likely, because it uses a Mini-B port)
I think you'd need to have a special driver to access the NAND (unlikely)
You'd need to download a Blackberry OS (unlikely and would probably need an old version)
The NAND (where the operating system is stored) would need to be larger than the Blackerry OS (highly unlikely)
The phone would need to be able to use the new OS. (not sure, but probably unlikely)
If you fuck around with the NAND and didn't make a backup, you could brick the phone (likely)
This is my best guess, I'm no phone hacker and I'm not sure if a SIM card could do it as I'm not really sure what SIM cards do in the first place (I've never had one)
Just tell her if she wants the phone, she better play the lottery before it happens because it's more likely.![]()
