after a lot of hard work I was able to find out how to run AIM on your psp! I wrote a little tutorial for one of my friends... he is computer illiterate and not great with the psp so it may sound a little stupid to you but here is it, figured I'd post it because i spent forver trying to do this and I'm sure it would help out some other people.
AIM and Internet on PSP
This will tell you how to get on the internet and get on AIM from your psp system. The grammar is terrible, but deal with it.
Hook up your wireless access point to the place where you would plug in the Internet cord. Now, get on your psp and make sure the switch on the left side is up so you can use wifi. Turn on your psp and go to settings, then scroll to the bottom and pick “network settings” goto “infrastructure mode” and create a new connection. You can now change it’s name, mine is called “beverage” then press the right button on the D-pad. Now it will say WLAN settings, go to scan and press right on d-pad. Now if the switch on the left is up it will scan for a sec and bring up a new menu. It should say “Select the access point to be used” select the one that has the SSID of your access point. Not sure which one it is? Try one that has the best signal and has no security and that is probably it. Press “X” on the one you pick. Now you will see what you selected where it says SSID. Press “right” on the d-pad (from now on I’ll just say -> cause I’m too lazy to say “right on the d-pad”) now it wants you to pick security settings, go to none and press ->. For address settings go to easy and press ->. Now it will show the settings, just press ->. Press “X” to save. Now press “X” to test your connection. If it works yay! If not, try again. Ok you now have a working connection now go to the web browser and it will ask you which connection to use. Or it will just start up. Whatever, just pick one or just let it start up. Press triangle and press up on the d-pad (as long as it highlites the address bar) once it is highlited, press “X” get used to the input keyboard, you will use it often. (for sites you hafe to type http:// before the site) put in http://www.e-messenger.net/. (takes a wile to load) type your sn in the aim thing and put your pass in there also. It will log you in! Ok pay attention now, this is the hard part.
Ok it gets harder still lol. If you want to IM, you have to press and hold square and L or R to view the different tabs, but they only stay up for like 2 seconds so you have to move your cursor to the input box fast. Click the input box, type what you have to say and press enter, the tab will probably close again but oh well. Press the square L or R thing again to view that page where you inputted text and press send really fast. And sometimes you may not hear from your buddy so once the tab where you did your iming is up try to press reload at the top right corner of the page.
Ok you can also try this, I just found out like 10 minutes after writing this. On the buddy list page, press triangle. Now go to “file” and press “close page” Now you can use the “square button R button” combo to switch to your IM windows without it switching back! YAY! But downside is, no more buddy list and you have to log in again to view it L but at least it works right?
One more quick reminder, once you are done with it, SIGN OFF!!!! OR ELSE YOU CANNOT RECEIVE INSTANT MESSAGES ON YOUR COMPUTER ANYMORE, THEY WILL BE SENT TO YOUR PSP INSTEAD!!!!!!!
