Extract iOS .IPSW from .DMG [How to]

Convert Apple iOS .DMG File to .IPSW – Apple is now always seeding their beta version of iOS as .DMG file instead of regularly .IPSW. However you’ll need the .ipsw version to restore via iTunes as well as to create custom jailbroken firmware either using Sn0wBreeze as well as PwnageTool.

So if you got -for example- iOS 5 beta 6 .DMG file and want to extract the .ipsw file inside it, so here it is nice common methods to do that.

Note: mostly people will say it as “convert .dmg to ipsw” but basically what we gonna do is to extract .ipsw from a .dmg file.

    I guess each one of us found another free tool to get the IPSW from the DMG file :)) Mine was DMG Extractor free, easy and I’ll use it in the future as well. Here is also the video that guided me through: http://www.youtube.com/watch?v=pX6vt9ulcKc&feature=plcp
