You probably know that you can have your iPhone both ring and vibrate by adjusting the options under Settings -> Sounds, but what if you want it to vibrate first, and then ring, as many other cell phones do?
A reader of New York Times tech columnist David Pogue’s blog wrote in to suggest one easy solution to this dilemma. Just create a custom MP3 ringtone, using Garage Band, and insert however much silence you want at the beginning of the ringtone—Pogue’s reader suggests ten seconds. Now your phone will vibrate before ringing, giving you a chance to discreetly excuse yourself before the opening strains of “Jungle Boogie” echo throughout your staff meeting, prompting pointed stares from around the table.
Hypothetically, of course.
you can download a silent ringtone from www.silentpodcast.com. Its great for when you don't want it to ring at all.
That's a great idea, I have no idea why I never thought of this before. How stupid of me hehe
