Would this work if i downgraded from Iphone4 4.2.10 to 4.2.8 or would the method be different i tried downgrading earlier today and my phone got stuck in dfu lol

This will wipe all your contacts, apps etc as you are restoring your iPhone.

If you have already backed up your iPhone with iTunes then you could restore your iPhone once you have restored.

Or the only thing i can suggest is try using "iFile" or "iphone Explorer" to look into your iPhone and copy your data onto your computer.

does this wipe all the data on your phone?

i mean: once i've downgraded the firmware, will all my stuff (contacts, apps, mail, etc.) remain intact?

if not: is there any way of recovering all of that automatically?

thanks
