If you scroll across to 'Settings' on your PSP's menu bar, there is a 'Network Update' option. Selecting this will download the latest firmware update.

If you connect your PSP to your PC with a USB cable, you can manually delete the upgrade installer from your memory card. This is not to be confused with downgrading the PSP firmware itself. Once you run an upgrade, the PSP's firmware is flashed and upgraded, deleting the update file won't do anything about that.
You just need to upgrade your firmware, then you can access the PSN to purchase and download games.
Well it's possible, but first you'll need an old copy of grand theft auto:liberty city stories. From this select the firmware upgrade to 1.5, which isn't an upgrade at all. The psp will then downgrade to 1.5 from the 3.30. From there you can install the custom firmware which you desire.
I'm not sure what you mean by "the mod" but I think you may be referring to a "custom firmware". If so, you can safely format your PSP's memory stick without removing the custom firmware. This is because the custom firmware is stored in the internal PSP flash memory, not on your memory stick. If you want to remove the custom firmware, you will need to just install an official firmware onto the psp. The easiest way to do this is to put in a PSP game that comes with a firmware upgrade and choose that option. Then I would recommend having the psp do a Network Update.
Skype works on PSP series 2000 and 3000. I understand that is comes with the upgrade of the firmware.
Unfortuantly fellow PSP player you yet cannot play iso's on your PSP. Persevere these few months until some gets a hack. To be on the safe side, do not upgrade your firmware. I really feel for you :).
New version comes out is the best version but i should be custom firmware because without custom firmware you can not play free games in PSP.
You may need the latest firmware, upgrade first and try accessing the games after.
what you need to do is downgrade then upgrade to the official firmware -- Erm, why would you WANT ofw? The POINT of CFW is that your PSP is free of Sony. I say, upgrade ur CFW to 5.00 m33.. -RLcTstealth
it depends on your psp. for example i am using PSP-2000 which i use firmware 4.01 and for my PSP-3000 i am using firmware 5.03.
