The Samsung Galaxy S II has arrived at U.S. carriers (AT&T, T-Mobile) in recent months after its debut in Europe.  The device is already being called the iPhone killer for its great form factor (thinnest 4G phone on the market), outrageous performance (using Samsung’s own 1.2 GHz dual core processor), large screen and advanced software capability.

Naturally, reviews of the new phone are focused on this dramatic hardware refresh. But also included on the device is Samsung Social Hub Premium, the email and social messaging app that is powered by SEVEN Networks. Social Hub Premium is a social networking and integrated messaging applications that uses the SEVEN push platform to give Galaxy users access to all of their communication touch points –voice, email, instant messaging, Facebook, Twitter, contacts and more – under a single, lightweight user interface.

When it debuted on the first generation Galaxy phone (Galaxy S), reviewers gushed over how its contact-focused orientation made it easy to track contact from friends across multiple messaging services.  One video review was titled: “Social Hub Makes Galaxy S Stand Out from Other Android Devices.”

On the Galaxy S II you have to dig deep under the hardware specs to find the love, but it’s there.  One business user proclaims the email simplicity: “stock Samsung e-mail app is absolutely fantastic…it works flawlessly.”
