Samsung Galaxy S, Front facing camera is not an option First off, I'm very very new to this. 
How do I activate my front facing camera in my Galaxy S? It's up to date on software according to the US Cellular store, I brought it in for an update not long ago

(I'm running hardware version I500.04, it's model number SCH-I500, firmware version 2.3.5, and kernel version 2.6.35.7, not sure what's necessary) 

When the camera, skype, or YIM is open, there is no option to change camera display. I'm not sure what to do, because it appears to have a front facing camera installed. 
Does anyone have advice? I've looked around, but haven't been able to find an answer that truly answers my question.

So...how do I activate this camera? It's a large part of why I bought the phone.
Open pre-installed Camera app &amp; tap this icon to switch cam:

Same icon is found in Camera360 Ultimate (my fav) to switch cam.
Front-facing cam is automatically activated during video calls over 3G (if you are using pre-installed Dialer app).
