why does my iphone buzz/vibrate in the cradle EVERY 20 SECONDS?
sometimes when I plug in my iphone to charge it gives the usual 2-buzz when it receives power, and then KEEPS doing it over and over. it is SO annoying. it's usually every 20 seconds or so, sometimes more rapidly, sometimes it does three buzzes in a row, every like ten seconds or so. unless you've experienced this, you have no idea how annoying it is.
so... why? and what can i do?

This happened to me on holiday, the power adapter I was using was broken.

Switch it off silent. Now see what noises it makes. If it makes the "connected to power!"/"disconnected from power!" noises it's a flaky power adaptor or cradle. Check the connectors for dust and try a different outlet.
Do you get the same if you plug the cord in rather than docking? Your iPhone may not be docking properly. Is it in a case?

I had a crap USB hub that I plugged my iPhone into, and it did this... it's super annoying, I agree. Most likely it's a bad hub or power supply.

Response by poster: thanks for the suggestions.
i thought of that and realized i was also using a keyboard, mouse, printer and external HD all off USB at the time. BUT, all of the above is running off a hub on the right side usb port, the iphone alone on the left side. the hub itself is unpowered. i guess maybe even though there's two ports on the macbook it's still just one bus?
i'll try switching off silent next time it's driving me crazy, thanks.

Response by poster: i should have mentioned this was docking to the computer, not the wall outlet.
iphone not in a case.
i wouldn't be surprised if the hub sucked, it was one of those sub-$10 impulse buys.

Oh, definitely overloaded bus, then. Try it as the only item plugged in (no hub), and if the condition stops, that's your ticket.
