The Motorola A920 / A925 / A1000 cannot vibrate and play a ringtone at the same time during an incoming call. Vibor makes it possible!
You can still use different ringtones, select a ringtone per contact etc. In addition, the mobile vibrates on incoming calls, SMS/MMS, email and alarms with selectable patterns.

On incoming calls, a contact's picture is displayed in the upper half of the screen - much larger than the tiny icon which is normally shown. If there's no contact picture stored to the calling contact, or the caller's phone number is assigned to more than one contact, name and/or companyname of all those contacts are shown. If the caller's phone number is not assigned to any contact in your phonebook, the number's prefix is looked up in a list of country- and local-area-codes, and the matching name(s) are displayed. This list can be edited to your needs! Additionally, the caller's phone number will be shown on every call, if you like.
