Skype did work for me on my phone (Samsung Infuse 4G) but, it can be slow and there can be delays in voice and in IMs (haven't bothered trying video since there are too many issues with voice and texting). Works fine on a wifi network but over cell network it sometimes works and sometimes doesn't. One big issue with Skype is when you close it after you are done is stays running as a service. Even if you kill it off with something like OS Monitor it will keep coming back to life and it will keep using battery and cell network data. Very annoying and very bad. Only way to permanently kill it off is to shut down the phone and restart, if you have Startup Manager, otherwise it will start up as a background service again automatically. This fact is so annoying I'm undecided as to whether I should keep Skype on my phone or uninstall it. Skype, if you are reading this then please fix the app to not run in the background as a service. I would use it a lot more if it would actually quit after use. Anyway, useful if you really need it, otherwise use something else like Google voice if you can. Skype for droid is not ready for prime time.
