To *do* the front camera, you'll first need to find a hole... and be prepared for some pain I would imagine.

If you want to use the Camera application to record video from the front camera instead of the main camera, unfortunately its not possible at the moment. There is no technical reason, Nokia just didn't write the code.

The front camera IS used for video chatting with other people through skype, SIP, or any XMPP Jabber enabled service. To use it in these contexts, first add the video-supporting service, login, and initiate a video call to one of your contacts. Note that there are certain instances where you may not get a Video Call Option for every contact. These instances are fairly well document and a Power Search (located in at the top of the column above Active Topics) will reveal them to you in short order. There's a whole forum post about it.
