I have recently had a iphone os4.1 16gb model and used limerain to jailbreak my device and now got a 32gb model which had os4.2 factory installed so cannot downgrade to 4.1 - my question is should I wait for a windows untethered solution for 4.2 jailbreak or can I just tethered jailbreak for now and then untethered jailbreak once it is available?
