Yep nowadays every psp can be hacked, doesn't matter what firmware its running but chickHEN is only for 5.03 and is pretty outdated now, i recommend you update to 6.20 pro b10 rather than 6.60 pro b10 only because 6.20 has a permanent patcher so you don't have to run the CFW loader file every time you start up your psp, look for some tuts on youtube if your stuck.
