Hello, There are two different options when we buy the annual B4i for IOS phones. One is 2 months free update and the other is 2 years free update. Is this update of the ide we developed B4i in Windows environment? Or is it an update of the IOS application we developed? That is, if I develop an application and it works smoothly, should I update my application with the updates that come depending on IOS over time? and accordingly should I update the B4i as well? Or will an already running app always run? Because I couldn't decide which one to choose between the 2-month option and the 2-year option. Thanks.
