After several months of work, and a couple beta versions sent to iOS developers for testing purposes, the new version of iOS – iOS 4.3 – has finally reached the Gold Master status, and will hit the street next week. Interestingly enough, Apple waited the week of the introduction of the second-generation iPad to launch iOS 4.3, which leads many to believe that the event scheduled at the Yerba Buena Center for the Arts next week will be for the introduction of both iPad 2 and iOS 4.3. As usual, the new version of iOS will offer many bug fixes, but most importantly, it will bring two major features to iOS-powered devices: the ability to subscribe to content via a new subscription mechanism, as well as the ability to turn your device into a Wi-Fi hotspot, in order to share your device’s 3G connection with up to five other devices via WiFi (note that the hotstpot feature will only be compatible with the iPhone for now). On a side note, the new subscription model offered by iOS 4.3 could end up being a major game-changer for the struggling newspaper industry. Since The Daily, the first magazine to use the new model, requires iOS 4.3 to properly charge its readers on a regular basis, expect News Corp. to ask iPad users to start paying for the magazine very soon.
