New Web-Based AIM Client for PSP
Wish you could send IM's to your AOL Instant Messenger (AIM) buddies from your PSP?
Now you can.
An enterprising group of individuals has come up with AimOnPSP,
a "web-based AIM client that can be used in almost any browser that
supports JavaScript (such as the one included in the new PSP
firmware)."
The service is free-of-charge. To use it, just point your PSP's web browser to www.aimonpsp.com
and input your AIM username and password. You can send and receive IM's
just like you can while using AIM, although certain features are
unavailable (such as file and image sharing).
