We have already discussed about IntelliScreenX which changes the way we think of notification center. The tweak has finally been available in the form of beta for free. It is only meant for public testing and you may experience some bugs while using it. However, the final, stable version would cost $9.99 from Cydia Store which would be free from any bugs.
IntelliScreenX is a level ahead in terms of the way we interact with notifications in iOS 5. You can do many more things from the notification center itself without opening any native apps. For example, you can tweet and reply to mentions from the lock screen as well as from the springboard. Also, it includes support for RSS feeds & Facebook which can be added depending on your requirements.
You can try out IntelliScreenX beta by adding this repo in Cydia: http://www.intelliborn.com/isxbeta. It’s definitely worth checking. Currently, only iPhone and iPod touch are supported. It won’t work on your iPad. Let’s know your first impressions.
