With a recent study showing a nearly 80 percent increase in smartphone shipments from a year ago, there are plenty of first-time smartphone users who may want a little help figuring out everything their advanced devices have to offer.

U.S. Cellular is hosting a free workshop at 8:30 a.m. Saturday at 621 Washington Square Mall in Washington to guide attendees through all of the features and functions of their Android-powered, Windows Phone and BlackBerry devices that can enhance their lives. All questions are welcome from current and potential smartphone users, and attendees don’t have to be a U.S. Cellular customer.
