Are you a Gtalk user? I am! lol
You can now chat with your friends on Gtalk, Aim and MobileMe in a very pleasant looking app, Verbs.
You can log in to multiple accounts on multiple platforms. File sending is made possible with cloud services like CloudApp and doplr.
You can switch between chat windows by tapping on the top left button. Swiping left/right lets you view all opened windows.
Here’s a look at the settings screen.
In my opinion, only get this app if you really really like the interface and is a hardcore chatter on the mentioned IM platforms cos $2.99 is quite a high price for a simple app like this.
