I know many of you are lurking around to see if there are any hacks for ipod to download messengers like yahoo, aim, msn messenger etc. Well sorry there is none (yet) but here is what I do!
Go to www.meebo.com with your safari browser. Click on the service you like AIM,YaHoo,MSN and others.
Login and that's it.
It works pretty good tho.
I tried other services like www.ebuddy.com but that does not work well.
