The Razr from Verizon has had that ability disabled. You can buy Motorola's Phone Tools ... speakerphone.Also can't turn off the startup sound like you can on most phones, nor the startup animation.

I have this phone for U.S. Cellular. Has S/W version GATW_03.16.02P and sports the Moto UI. Simply the best! - USCC graphics = lousy. The USCC logo at startup ... Well done Motorola and U.S ...
