Can i use the yongnuo RF-602 on my Nikon D3100 and my SB-700 flash gun?
Yes.
And most of the time it will work great.
A few things to keep in mind:
these things are designed to eventually fail. It might take one month, it might take 4 years. It is hard to tell, and if you are relying on them, they are the most likely to break down leaving you with a shoot you can't finish.
They are backward compatiable. You can't use them with the 601 or 603.
Bottomline,
The ideal price to try, but they have a number of short comings that make them infeasible in the long run.
I did start with the 602 when i was not sure, i later upgraded to phottix. Pocketwizards are the industry standard.
