Hey Ryder, these may help
GO! Messanger and
PSP is Go! Go! Go!
Man, this would be sick. Alot of my friends are getting the PSP now(since I get one, same thing happened when I got a DS a couple years ago, lol)and this would be so useful. I think that an email system would be awsome too to add to this.
My idea I have been thinking for awhile, why not take advantage of the home button that you can press to always to get to the XMB. Why not have it set up sort of like the 360 where you can access other things through this. Why not also have whenever you have your wifi button turned to on, that people can see that and call(will be sent has a page) and or text/email you. Then when playing a game, an icon will pop up saying that "Blahblahblah would like to chat" or "New Message". Then to see the message/get into a chat you can click the button and choose. What do you guys think?
