Howling:Was Jack's wrist device always meant to be a vortex manipulator?

Did Jack always have a vortex manipulator? It seems that the first instance of this name in Doctor Who was in Utopia, 2 years after it was introduced. Jack used it to scan, project holograms and communicate with others. I know he was a time agent but they might have been issue time ships instead of a time travel device connected to their wrists. I think that after series 3 this version was just accepted as true so river and john hart were given this version. He never used it for teleportation on screen, especially when it would have been useful. Examples are as follows:

Most important 1-When the daleks were about to exterminate jack, why didn't he teleport out?

2) When jack, rose and the doctor were cornered either by the gas mask zombies or when they could not leave the room in the hospital (the one where the doctor and rose dance) in the episode the doctor dances. Jack instead used his ships teleport.

3)Again referring back to the doctor dances, why did jack not teleport out of his ship when it was going to explode? And it has been shown to work as an interplanetary teleporter as seen by his trip from satellite five in 200,100 to earth in 19th century and from malcassairo in 100 trillion to earth 21st century. So why not use it? --Coop3 ☎ 18:21, June 29, 2013 (UTC)

4) When they were rushing to save rose from the anne droid, when the doctor could not get in with the sonic, why not teleport in? Although you could argue the door blocked this function.


 * The vortex manipulator didn't always function as a teleport. It only did that after the Doctor "upgraded" it in "Utopia". So that's why they didn't use it as a teleport in all of those other instances. Ensephylon ☎  22:40, June 29, 2013 (UTC)
