Looks like WhatsApp just got updated to fix a couple of major bugs for Samsung and ICS users. If you’re not familiar with WhatsApp, it’s an app that allows you to text people using your data plan, not your texting plan. It also has quite a few cool features along with group chatting, and the best feature is that it’s completely free! You can also text international for no additional charges, pretty cool app right? WhatsApp is one of the most popular Social apps in the Android Market right now, and is available on every smartphone platform including Blackberry, Symbian, iOS, and webOS.

Here’s the full changelog for version 2.7.3581:

1. Critical bug fix for Samsung devices that would “lose” their registration
2. Notification coloring bug fix for Ice Cream Sandwich devices
