According to a New York Times report, citing two unidentified Facebook engineers, the popular social network is completely revamping its iPhone app to give it a notable speed boost.

As per the information shared by the two sources, the overhauled Facebook iPhone app - which will boast optimized speed for iPhone users accessing the social networking site on the their handsets - is currently being tested by the social network's developers.

The sources also revealed that the new version of Facebook's iPhone app will be released in July; and though it will work faster than the previous version, there will hardly be any other noteworthy difference between the two versions.

Going by the report, the enhanced speed of the new Facebook for iPhone app will essentially be a result of the fact that the new app has been built chiefly using the `Objective-C' coding language.

Noting that the current Facebook app also uses Objective-C, but only for its shell, while most of its components are built using HTML5, the newspaper report said that the present approach could be described as "putting the engine of a Smart Car in the body of a Ferrari."

Meanwhile, about the speed improvement that has been brought aboard the new Facebook iPhone app, New York Times technology columnist Nick Bilton said: "I had the opportunity to see the as-yet unreleased iPhone application, and it is fast. Blazing fast."
