How can I find the camera specs of an HTC Wildfire S for matching a virtual camera?

I want to match a 3D/CGI virtual camera to photos shot on an HTC Wildfire S. I need basic camera parameters such as focal length, sensor size, aperture, ISO behavior, and anything else that may help recreate the real camera in software. The phone manual and general web searches don’t provide much detail. What’s the simplest way to find these specs, and what values are known for this phone?

A search for HTC Wildfire specifications returns very little information about the camera, but searching for specific attributes like "aperture" and "focal length" yeilded some bits and pieces. Wikipedia also had an article on sensor sizes (fourth reference below):

A practical first step is to read the photo’s EXIF metadata. The Wildfire S writes at least some useful camera data into image files, and you can inspect it on a computer or via a photo service like Flickr.
From the community answers, the HTC Wildfire S appears to use approximately:
- focal length: 3.5 mm
- aperture: about f/2.2
- resolution: 2592×1944
- sensor size: probably around 1/6" (about 2.4 × 1.8 mm)
- ISO: variable; examples given were ISO 75 and ISO 400 depending on light
For CGI matching, the most reliable value to pull directly from your own image files is the focal length in EXIF. ISO may change automatically, so check each shot. Sensor size is often harder to confirm for phones, so if your software requires it, the approximate 1/6" value may be the best available estimate from these answers.
If you need more exact camera matching, use EXIF plus visual calibration from the photo itself, since smartphone specs are often incomplete or inconsistently published.
