We’ve seen a few apps that promise new ways of unlocking your Mac, but Tether, a new free app, might be the easiest yet simply because you don’t need to do anything to use it.
Tether is a pair of apps you install on your iPhone and Mac which detect how far your phone is from your computer using Bluetooth, and automatically locks it when it’s further than a few meters away.
If you need to restore your iPhone, but can’t afford to lose your jailbreak (especially since iOS 8.1.3 isn’t jailbreakable), here’s how to restore your iPhone without losing your iOS 8.1.2 jailbreak.
Whether you want to just start from a clean slate, you’re selling your jailbroken iPhone, or you screwed something up on the software end, you’ll want to completely restore the device. However, restoring your iPhone through iTunes will force you to update to iOS 8.1.3, and since this latest update isn’t jailbreakable yet, you’ll want to stick with iOS 8.1.2.
Luckily, there’s a way to restore your iPhone while keeping your iOS 8.1.2 jailbreak intact.
