Iphone Webbrowser, Fullscreen, No Buttons, Audiosupport, Running in Background

Hi Coders, I need this: A Webbrowser for the Iphone/iPod Touch with the follwing Details: 1: No Buttons at all. Only the Startpage must to be set in Settings. But no Adress can be entered in the Browser and no forward/backward-Buttons. 2: Browser must be able to play sound 3: Browser must also be working in Background (after Homebutton or Sleep/Powerbutton was pressed) and any JavaScript must continue working 4: Must support all standarts, like Safari does, e.g. HTML5, JavaScript, etc. No Flash Has to work on iOS 6.1.2, No Jailbreak, if possible. Thanks!
