Earlier this week, we learned about plans to finally deliver an update that enabled, among other things, placing voice calls over a WiFi connection for the HTC Amaze 4G on T-Mobile. The history of that update, which a leak had previously identified as planned for arrival in mid-November, was closely tied to that of the Galaxy S II. In fact, when we finally heard an update on the rumor that claimed the new software would show up this month, it specifically referenced the GS2 instead of the Amaze. Despite that, we saw the Amaze make the upgrade on Monday, with the Galaxy S II seemingly left behind. It turns out it didn’t have long to wait before catching up, and today T-Mobile has announced system software T989VUVKL1 for the GS2 is on its way out.
Gingerbread itself gets a minor upgrade on the T-Mobile Galaxy S II, moving forward to 2.3.5. The addition of WiFi calling is probably the most notable component of the update, allowing you to both save on your plan minutes and maintain a strong connection even when in dense, urban areas. Beyond that, you’ll also find unspecified improvements to the phone’s handling of Caller ID and see somewhat improved battery life thanks to power management enhancements.
The update is on its way out to Galaxy S II owners now, and should hit everyone within a few weeks.
