I don't think it's possible to video chat on Skype through PSP, it might be possible, I don't know. You can try posting in the Playstation forums asking them or something.
Yes, you can chat on Skype and Go messenger.
There is a good website for chat called psp mod. Psp mod is actually a website about psp modifications but you could also sign up for it and chat online. Another one you could use is skype, but skype is not a website. you have to download it from the internet. skype is much better than internet chatting because when you chat, the messages you or the person you are sending comes into the chatroom faster. you can also do video calls on skype. the video calls wont require money (from a sim card)to call other people,it only takes internet allocation.
Nope
you can only get skype for psp 2000 and 3000
skype cam my psp
first of all, skype for psp is only available on psp 2000 and 3000, on those, skype comes with the system updates
In order to get skype you need to upgrade your psp to at least 3.90(only for slim). The other psp I'm not sure of.
No
i believe Skype is free to use and download on PSP-2000 and 3000 Series and even the PSP Go. However the "fat" PSP as some people call them, i don't think they have Skype compatibility.You can also buy Skype Credit to use to call home phones or Mobile phones, but this is Optional. Skype to Skype Calls are free :)
update it
you can call with skype on the psp 3000 and psp go
If you load Skype on your PSP, you can use the Skype Headset to make free calls.
