After reading up on custom firmware and jailbreaking devices in general, I've decided to get a Cobra USB for the added functionality it provides. I have
some questions before buying it though, which I hope the people here can help to answer :

1. Is the Cobra USB setup procedure "brick-proof?" I'm not too good at technical matters so I'm kinda concerned about doing something wrong. I've also
heard that some of the custom firmwares can brick your PS3 if you do something wrong, another reason I decided to get the Cobra.

2. What are some good sites to order it from? (I live in Southeast Asia BTW)

3. Does anyone here have experience with the Cobra USB? Works fine, everything in good order etc?

I have a slim PS3 with official firmware 3.55. Hope someone can help with the questions!
