Granted. But you were responding to somebody who was talking about about the fact that 3G video calling has been available for years. Your response only mentioned Skype. I just wanted to make sure it was clear to everybody involved that Skype is absolutely not the sole example of previously existing 3G video calling technologies - and that an officially ratified, truly open standard for 3G video calling already existed before Apple upped the ante with Facetime.
