Actually I already bought Windows Mobile 6.1 phone since 2009, but I started to use it just now. The problem occured because there’s no official yahoo messenger application from Yahoo! itself. So I start to find 3rd party, and found Palringo. Yes, this awesome stuff (also free) can let you get connected to Yahoo! buddies from your Windows Mobile 6.1 phone. Palringo for Windows Mobile 6.1 can be easily download from here.

The pros of using Palring as your Messenger Apps are :
- lightweight apps
- easy to setup
- can do many Yahoo! ID also others messenger ID

and the cons because of Palringo is :
- can drain your battery faster haha (joke..)
