GadgetLuvR,

I think the FAQ has some summary details. It's complicated and the jury is still out on many patches.

Depends on which phone you have.

The ZIP patch that copies XV6600 Bluettoth stack to PPC-6601 has had the most success.

The rest I'm not sure about yet.

You need to be pepared for hard resets (without complaints) if you want to experiment with patches.

No risk no reward though
