Yesterday evening, T-Mobile announced their first update for the Samsung Galaxy S4. The update will be rolled out instantly via OTA and over Samsung’s desktop application, Kies.

As we get closer to Samsung’s long-awaited Galaxy S IV event in Times Square later today, the rumor mill is working overtime. According to a source for The Wall Street Journal, Samsung’s new handset will come with SwiftKey Prediction Software built-in.

A number of new Galaxy S IV case images have made their way onto the web, courtesy of our friends at MobileFun. They sport a slightly different design than those that surfaced earlier this month, and they support the latest leaked photos we’ve seen of the Galaxy S IV.
