I finally updated to 2.1 yesterday with the SDX kernels, and I've noticed (among other things) that my phone does not vibrate on notifications of e-mail or text messages, even though I'm specifically telling it to do so. It doesn't do it when the phone's on silent, vibrate, or at full volume. In fact, there's a "test" mode in HandcentSMS and ever though vibrate is set to "Always," it doesn't vibrate, even when I tap on "Test notification." Even if I set the main control to vibrate when a call comes in, email and texts still do not cause a vibration. Has anyone seen this? I apologize if this has already been spotted--if it has, if you could point me to the link, that would be great.
