Twitter is punching up its mobile experience on iPhone with more visual interactivity and slickness, according to 9to5Mac.com. The upgrades and updates were leaked on Apple's App Store.
Twitter for iPhone 4.3 will have content previews, videos and images. The autocomplete function is also getting an upgrade.
Another change is the push notification as users can now choose who they want to notified of when that person is active. Tapping a user's avatar taes the tapper to that person's profile page.
The release notes also highlight that users can manually input passwords when having authentication issues.
So, probably within 10 days or so, look for the new Twitter logo for the new Twitter app in the App Store.
