The app, now officially called Twitter for the iPhone, offers browsable hot tweets and search for tweets from nearby Twitter users and top trends — all without logging in.
And now new accounts can sign up for Twitter in the app without having to go to Twitter's website.
The app works for both iPhone and the iPod Touch, just like Tweetie. But Tweetie 2.0 cost $2.99; Twitter for the iPhone is free.
Adult industry professionals — particularly performers — have embraced Twitter for marketing their brands.
XBIZ.com and XBIZ.net even have a presence on Twitter. XBIZ.net recently introduced a new feature to make tweeting easier and more efficient for industry professionals.
The feature allows XBIZ.net users to post their status updates on both XBIZ.net and Twitter simultaneously.
