Facebook released today the new 2.0 version of its iPhone app, which is designed to significantly boost its appeal. The company prepared an update meant to transfer most of the functionality of the full Facebook version on to the mobile device by adding several new features.

The 2.0 includes friend requests, notifications, message attachments, inbox search, people search, photo tagging, photo captioning and full News/Mini Feeds. The new features were requested by many users as there were several problems and miscommunications between the users of the iPhone app and Facebook’s members that used a regular browser, with one of them being that the messages didn’t display the attachments.

The 1.1 version of the app was considered a disappointment for most iPhone users, who were anticipating an updated version.

This is just one of the many apps available in Apple’s App Store. The service turned out to be extremely successful, and even though most of the applications are free, it managed to bring in more than $30 million in its first month and it is still going strong. Even though it was initially created as a service meant to boost the sales of the iPhone, it seems to be doing very well on its own.

There have been some issues caused by the company’s policy to decide which apps enter the store and which get blocked. The selection takes into consideration a series of factors and some developers are frustrated that their work is not appreciated. Apple is being criticized for its selection process that should be a lot more transparent.
