Now, for iPhone folks, if you want to do a little retro bbs direct dialing, I've found a way, but not for us Android folks yet. This means plugging your iPhone into a USB acoustic coupler. Yes, 300 Baud, but it's workable! Then drop in a handset & dial away! The article author's solution for the next time his kid goes back to China & The Great Firewall blocks his facebook, his kid just finds a payphone & calls home, for unfiltered internet!

Frankly, this has tempted me to get an old inactive iPhone, just for the BBS's that I can't yet otherwise reach, but my hometown no longer has any 24/7 payphones! There might still be one hiding, at our old Pizza Hut, as I haven't looked or used it, in years!
Above all, have fun!
