Did they say they would contact you? I know a lot of places specify that if you haven't heard back by X days then to assume your application hasn't been successful. Also, did they give a deadline for applying? Some places won't call anyone for interview until they have all the applicants in.
Anyway, I'd give it a little longer before calling them... and make sure you call during office hours (Mon-Fri, 9-5 usually, but some places may have different working hours so check). It may actually work against you if you call (and possibly annoy) someone during their personal time.
