How strong is the vibrate on the Charge? I have noticed that every new phone I get the vibrate keeps getting worse and worse. The Nexus S I have now and can't even feel it going off in my pocket and sitting on the desk in front of me its like it isn't even moving. I miss how strong the vibrate was on the original BB Curve and wish manufactures would bring that back, I could feel it when it was in my front suit jacket pocket.
