Android 2.3.5 update for T-Mobile's Samsung Galaxy S II

T-Mobile is said to be introducing a gradual roll out of the Android 2.3.5 Gingerbread update for their Samsung Galaxy S II smartphone, going by the name software version T989VUVKL1. T-Mobile claims that those who install the update will benefit from various improvements “based on customer feedback" – and to put it in a more specific manner, this update will offer Caller ID enhancements, battery enhancements, and Wi-Fi calling enhancements among others.

T-Mobile says that this update is not compulsory, so basically, it you aren't having any issues or troubles with your Galaxy S II, then you can always put off the update. Apart from that, this update will be made available over-the-air (OTA), so you can forget about it being a manual download. It might take some time over the course of the next few weeks to see this update appear on your handset, hence being patient is a virtue here. [Support Page]
