i just noticed I wasn't getting any vibration when I get a call. Pressing home button gives a vibrate, so I made sure vibrate is on for calls and tried a ring tone. The ringtone plays and phone vibrates for half a second and nothing more. I try another ring tone and no vibrate. Sometimes I get a slight vibrate when I choose things but it's only the jolt type of vibrate nothing like a buzzzzzzzzz. I tried to shut down and restart. That didn't help Any other ideas before I take it to apple and wait a long time for a replacement phone?
