If you have an e-mail address from the company to which you applied, it is perfectly acceptable to follow-up on the status of your application. I would wait two weeks, however, from your application date to follow-up, as recruiters and hiring managers can be pulled in multiple directions. You may also wish to return to the site at which you applied as many systems that companies use display your current status in the recruiting process. If you cannot determine this on their web site, then I would recommend that your initial follow-up be via e-mail. That e-mail should be very casual and relay the message that you are very excited about the opportunity for which you applies and were just curious about the next steps. This reiterates your interest level without being too pushy. If after two more weeks, you still have not heard something, a phone call follow-up with the same tone and message is perfectly fine.
