I recently received a PBUDY JailBreak clone PS3 modchip USB device in the mail from ModChipDaddy.com.
What I discovered in my recently delivered DHL bag was a ball of bubble paper wrapped up with layers upon layers of tape. Inside said ball was a box for a plastic maze money safe, inside that box was a wrapped up shopping bag and finally inside that were two nicely presented PBUDY PS3 JailBreak devices. Amazing stuff.
I proceeded to simply test the device on my PS3 - It worked. I plugged it into my computer and - Nothing obviously.
So... Here's another clone that surely does JailBreak the PlayStation 3.
