Shortly before the launch of the Apple Watch, the company from Cupertino has released a new iOS version: iOS 8.3. This release is supposed to bring more speed.
The list of bug fixes and changes is quite long - especially bugs with WLAN connections, CarPlay, Safari were fixed. Interesting for many customers: some providers now offer an explicit choice between 2G, 3G and LTE, according to first reports this works for Vodafone and Telekom. With Congstar the choice is also possible, as long as you have tariff with LTE support has.
The update to iOS 8.3 is delivered Over-the-Air (OTA) as usual with Apple and is available for iPhone from 4s, iPad (from 2) and iPod touch (from 5G) - Apple thus also supports relatively old devices, the iPhone 4S was introduced in 2011 and is thus almost four years old - without any Android to tease, correspondingly old devices are rarely supplied with current Android versions.
Besides the obvious changes, Apple will also have closed security holes again - especially for those who have Jailbreak should, as always, wait with the update: without known gaps, a Jailbreak not possible, as always it will probably take a few days until the "liberation" of the current iOS version is available.
