Jelly Bean update for T-Mobile HTC One S now being tested
2
Apparently, the carrier has already begun testing the update with the help of devoted volunteers, who are now checking out a beta version of Jelly Bean for the T-Mobile version of the One S. Once the testing is done and the carrier has made sure that Android 4.1 is ready for prime time, the update will start rolling out. Sadly, we don't know when that might happen exactly, but we'll keep you posted as soon as we get an update on the matter.
