Hello. Currently this is not available to install on your iPod. This and my other iDevice icons like it are part of a winterboard theme that I am currently working on. The full theme should be finished by the end of August and will be available for download on Cydia.
If you have any more Questions please do ask, I'd be more than happy to answer them.
Yes, soon this be on an actual iPhone. I am currently working on this as a complete winterboard theme. The whole theme should be complete in about a moth or two, if you like to see more start watching I will be releasing previews of each icon as I get them done.
