This week at the Mobile World Congress, some new devices were unveiled that will make it much easier for on-the-go consumers to access their Facebook accounts. Mobile – and social – marketers should take note.

HTC launched the Salsa and Chacha Android phones at the Mobile World Congress in Barcelona. Both phones have a branded Facebook button, creating a seamless mobile and social experience for users.

In a related blog titled “A Better Mobile Experience,” Facebook says the HTC devices give users one-touch access to Facebook Chat, Message and more. Users can also see friends' statuses and birthday info when they place calls.

In addition to the HTC phones, Facebook says it's partnering with INQ on two more Android devices – Cloud Touch and Cloud Q. These smartphones give users single sign-on options, and make a user's News Feed his or her home screen. Brands may like this, as it means frequently updated social content will literally be at users' fingertips. Moreover, the INQ devices make it easy for users to check into their favorite businesses with Facebook Places.

Another mobile development pointed out in the Facebook blog that marketers may like is a Facebook app for feature phones. Developed in mid-January, this app works on more than 2,500 non-internet-enabled phones.

These developments, Facebook says, are part of its effort to provide a positive mobile experience for the “hundreds of millions of people [who] access Facebook from their mobile devices to share and connect … whenever and wherever they want.”

Indeed, the latest comScore mobile report (which Brafton covered earlier this week) indicates that social networking is one of the fastest-growing content categories among mobile users. Still, the report showed that more mobile subscribers accessed news information than visited a social site in 2010. Brands may find that delivering custom news content via social networks is a valuable way to engage mobile social users.

Katherine Griwert is Brafton's Marketing Director. She's practiced content marketing, SEO and social marketing for over five years, and her enthusiasm for new media has even deeper roots. Katherine holds a degree in American Studies from Boston College, and her writing is featured in a number of web publications.
