If you have a feature phone, and it runs Java apps, you can still get Skype Lite even though Skype has officially discontinued it, and pulled all download links from their site. I found copies on Softpedia. They may have versions for other makes of phones, as well.
I did this because my Sony Ericsson W760a died -- the backlight does not come on. In their infinite wisdom, SE does not allow one to backup applications, merely data. The phone I got as a replacement is a SE C510a. It has a better camera: same resolution, but with auto-focus rather than fixed focus so it does focus closer than about 3 feet. Since I'm definitely getting an iPhone in a few months when my contract is up, I decided not to get either the C902 or K850i merely due to the admittedly small price difference.
