So this is a second hand PSP, it already came with the custom firmware PRO-B10 6.60. So I found that the Skype icon was not appearing, PSN works fine, everything is great, I can see some apps, installed some random internet app, in the USB viewer I can see the skype files. But the icon doesn't appear in the XMB. So I removed PRO-B10 and installed PRO-C, everything is good, but the icon is still missing. I removed PRO-C and tried to run Sony's firmware, it says I already have 6.60 installed. What can I do to get skype here? It's a PSP 1001, I think it's slim.. I could be wrong. Help, anyone?
