Second, about the upgrade of the old jailbreak equipment.
For jailbroken iOS devices, OTA (that is, direct update of mobile devices) method is not feasible, and it is forbidden when jailbroken. You can only get to the latest version by downloading firmware and refreshing the machine.
Third, the iOS 7 update log
9.28 After updating 7.0.2, most people reported that the power consumption was too fast. Pay attention to the small partners with high power requirements!
9.27 Apple updated iOS7.0.2, and added Greek as a language option to input password instructions for the bug that bypassed password protection. But what I look forward to most is the new security function, which fixes the situation that Chinese keyboards sometimes can't type Chinese. This update does not involve the jailbreak part of ios7 under development, so you can upgrade with confidence.
9.26 If it is an iphone4 device, it can be restored from iOS7 to 6. 1.3. Note: Only A4 chip equipment, other equipment cannot be degraded.
9.25 ios6. 1.3 and 6. 1.4 should be considered whether to upgrade, because these two versions are likely to escape in the near future. Of course, iOS7 jailbreak will also be released, but because different gods are developing, the release time will not be consistent.
9.24 If you get stuck typing on your iPhone4 iPhone4s, log in.
ICloud, and then close the "documents and data" item in the settings, and the problem can be solved satisfactorily.
9.22
IOS7 supports the simultaneous connection of 3G, 4G cellular data and WIFI network. If your wifi doesn't work properly or doesn't work, the phone will automatically switch cellular data to support the use of necessary applications. PS: Please pay attention, especially Unicom 3G users.
9.2 1 Apple has closed the verification channels of 6. 1.3 and 6. 1.4, which means that you can't downgrade back after upgrading iOS 7. Please think twice.
