T-Mobile late Thursday announced that it is now safe to download iOS 10.
“Apple has addressed an issue with iOS 10 which was causing T-Mobile customers with iPhone SE, iPhone 6 and iPhone 6 Plus to lose connectivity in certain circumstances,” T-Mobile said.
Those who downloaded iOS 10 before Friday can go to Settings > General > About to install the fix. If you have not downloaded iOS 10 yet, feel free to do so at your convenience.
