Twitter already has its official application for Android. With Twitter for Android we can go to our contacts in the social network easily and without any problems.
Twitter for Android has references, lists sections, retweets, direct messages, and can synchronize your contacts. We can add our contacts in the phonebook, or update the contacts that we had earlier in our agenda. In addition, the Twitter for Android has an aspect that seems pretty good, which emphasizes simplicity.
You can download from the Android Market, or from mobile.twitter.com.
