psp 3000 & 5.02

what can I do with this?

 

Nothing cool.

The 3000 series is currently un-hackable.

There is a exploit if you have the game GripShift, but nothing much has come from that...

 

I have GRipShift, what can I do with that

 

Here is a link to get some of the GripShift exploits

Download them and read the readme files.

If you upgrade to 5.03 the exploit will no longer work...
