Improve Image Quality by Upsampling

My cell phone camera is usually the only camera I carry and I’m not ready to give up my 2 megapixel camara\corder just yet!
Galen Fott of PC Magazine has written up a guide to improve your low quality images. Via a process called "upsampling" you can greatly increase the quality of images you've captured with your camera phone, for example:
Upsampling is an image-editing process that enlarges your original photo, making up (or interpolating) additional pixels to fill in the gaps. There are several upsampling techniques, and professionals are divided as to when and how the method should be used. In truth, the best technique for one image might not be ideal for another.
Galen covers a few techniques that you can try out with most image editing software. As well he talks briefly about third-party applications that can do the heavy lifting for you. The techniques are pretty easy to follow and while he asserts that they can't work miracles, they should help.
