Recently used a new chat client called imo.im on my iPad 2.
It’s is a great free app to have. Firstly, it helps you out in a great way by bypassing the main Facebook page if you just want to chat with your near and dear ones, but you are on a slow EDGE, GPRS or wi-fi connection. It integrates all your friends or buddies as the company calls it, in one place. No need to juggle between websites or different clients.
Before this I was a nimbuzz fan, I used to chat on a java feature phone, Samsung s3310 with it.
But when I searched for it on iPad it was just there for iPhone, everyone hates using 2x mode on iPad for iPhone apps.
So I found this great app, which met all my needs.
Try it out at the apps store. It’s worth the appreciation it is getting.
