The highly anticipated Samsung Mobile Unpacked 2012 event is minutes away, with fans gearing up for what is expected to be the official release of the Galaxy S3 phone.

Rumors, reports and leaks have been churning off from the success of the Galaxy S2, which was unveiled at the Mobile World Congress (MWC) last year, and was heralded one of the best phones of 2011 for its sleek design and lightning-fast performance.

The Samsung S3's delay, the release of the Galaxy Nexus and Note, the teaser countdown clocks and videos have all added to the hype, and Samsung enthusiasts gathered outside the Earl's Court Olympic arena and Phones 4 U, are expecting a significant rival to the iPhone and Samsung Galaxy predecessors.
