These tweak developed by Ryan Petrich & Nikos brings an exciting feature to the iPhone/iPod. They give the ability to receive and send any type of files to and from your device. This is esspecially useful for files such as .deb files, which allow cydia packages to be installed to your device without launching cydia.
As useful as these tweaks will be for certain people, this is definitely not a necessity, and I can’t see an end user who jailbreaks mainly for the fun of it getting any real functional out of these two.
ReceiveAny is available for free, SendAny will set you back $2.99 both in the BigBoss repo.
