The Redsn0w untethered jailbreak for iOS 4.2.1 is still in its testing phase among Mac users. Once this is complete, the tool is likely to be opened up for Windows users for testing before a public release will happen. While that is likely to take some more time one interesting piece of information that has come out is that this new untethered jailbreak solution will allow users to large size install custom bundles that was hitherto not possible.
In a tweet conversation, popular Dev Team member, MuscleNerd has pointed out that this feature is likely to be one of the benefits in this new tool.
@MuscleNerd Once the new redsn0w is out, will it allow to install custom bundles > 100 MB?
@i0n1c yeah that’ll be one of the side benefits of this new “upload to running ramdisk” capability
