Just got my hands on one of the samples sent out from PS3Yes crew/team. Nothing different from the other clones. It works as it's suppose to and YES it is upgradable. Oh yeah btw it came pre-flashed.

Pictures of the PS3Yes Package:Quote:
About upgrade: Plug it into PC, after 20 seconds; it can enter upgrade mode and both LEDs light. The PC will find device "AT90USB162 DFU", you can download firmware from us and use FLIP to flash it. If you install the FLIP and install drivers for "AT90USB162 DFU", you can flash HEX files that download from us and keep the "auto enter upgrade mode" function. You can flash it with any HEX file, BUT you will lose the "auto enter upgrade mode" function, after this, next time you have to do a hard upgrade. We are preparing more detail document for how to do a hard upgrade for PS3YES!.
