If you're talking about something like the Bell Jet Pack, they're out, and have been out for many years (conceptualized in the 20's and built and flown in the 60's). It's just that they aren't too practical, and come with built in hazards. Their range is short, and failure can easily kill the pilot. A link is provided to the Wikipedia article, and you can read more about this "James Bond gizmo" there.
Unfortunately, there are no jet packs in existence.

Gomu erasers come in 1 packs where you can't see what you are getting. They come in 3 packs where you can see two and one is hidden. They also come in 6 packs where you can see three and two are hidden. 1 packs come in at $1.00. 3 packs come in at $3.00 and 6 packs come in at $5.00.
There aren't any jet packs in GTA IV. If you're playing this game on the PC, though, there are mods that allow you to use a jet pack.

Jet packs. There is not a helmet, but I highly advise it. ;-)
