In RAD Studio XE4 there is support for the iPhone 5 form factor, there is a device in the drop down selector on the mobile designer, called iPhone 5, which switches the designer to those specific dimensions.
Also, you can select which device to be selected on the designer when creating new forms, this is quite useful if you are designing your app for an specific form factor, and you want any new mobile form created to use that device by default.
And finally, I’m showing how the application can use the whole screen real state of the iPhone 5, because we are supporting the iPhone 5 splash screen specification, and also, using the BorderStyle property with a value of bsNone, you can get ride of the status bar.
