So I saw this portable application the other day called aMSN. I know that AFKIM works, but it uses bitlbee and it's not very pretty. Don't get me wrong, I love AFKIM, but I use only MSN and AIM, and MSN way more.
aMSN is open-source...so someone should totally make a PSP version of it. It has a lot of features that aren't found in AFKIM.
