iPhone OS 4 BETA

iPhone OS is the operating system running on the iPhone (both original and 3G models) and the iPod Touch. It is based on a variant of the same basic Mach kernel that is found in Mac OS X. iPhone OS includes the software component “Core Animation” from Mac OS X v10.5 which, together with the PowerVR MBX 3D hardware, is responsible for the interface’s smooth animations. The operating system takes up less than half a GB of the device’s total 8 GB or 16 GB storage. It is capable of supporting bundled and future applications from Apple, as well as from third-party developers. Software applications cannot be copied from Mac OS X but must be written and compiled specifically for the iPhone.

To Upgrade using iTunes: Your iPod should show up in iTunes when plugged into your PC/Mac. Click on your iPod’s name. Press and hold SHIFT then click update, now find the OS 3 file. For the iPhone it should be “iPhonex_x_4.0_8A230M_Restore.ipsw”. For the iPod Touch 2G “iPodx_x_4.0_8A230M_Restore.ipsw”. Choose Open and now iTunes and your iPod/iPhone should be doing the work for you.
