Apple, in its newest move, has released the first patch, 10.3.1 update, a week after launching the iOS 10.3 for the iDevices, namely the iPhone, iPad, and iPod Touch.
On the feature front, the new security fix, 10.3.1 update, pivots on the Wi-Fi-based concerns, where a potential attacker can execute arbitrary code on the Wi-Fi chip. With this update at the disposal, such attempts have been made ineffective.
The next issue, which has been decisively addressed with the update, is the older 32-bit devices, still compatible with iOS 10. Such devices are iPhone 5, iPhone 5C, and the iPad 4th generation. Until last week, the 10.3 update was not accessible through OTA on these devices, and users were compelled to the use iTunes. With the launch of 10.3.1 update, users now can download the update through OTA again.
