The first "iphone" (Score 4, Informative)

Back in early 1995 a company called Vocaltec released a program called "Iphone" for Windows 3.1 that allowed PC to PC voice calls. It used EFnet IRC channels for the handshake which pissed off a lot of server administrators because the program couldn't function as a standard IRC client. The only thing an iphone user could do was connect to an IRC server, join #iphone channels and initiate calls with other iphone clients.
