Can my two male syrian hamsters live in the same room in different cages?

I have 2 male hamsters in different cages, their cages are right opposite each other in the same room. One of hamsters seems to be a little bit nervous however this could just be him getting used to his new home although i have had him since 15th May 2008. I got them both at the same time from the same pet shop where they were housed together. Should I keep them in separate rooms or will they be okay?
