Does anyone know the details of the tiff hack/fix showing in the newest version of the installer
i believe it is supposed to be under "tweaks" in installer
Well, you would have already had to jailbreak'ed your Touch to run this patch. The patch won't undo what has already been done. It just patches up the TIFF exploit if you load a later image in your browser.
Plus, you can always restore everything to default if you needed to.
