if you want to be able to voice dial, do not buy the htc sensation. the voice search doesn't work with bluetooth, and the phone is incapable of voicedialing. if you manage to get the apk for voice dialing installed,it will only force close on the phone; and other people posting in this forum will happily lead you astray and tell you to use expensive third party apps that will not work anyway. vlingo is the most commonly refered app and though it is free,it is not available for the sensation and if you manage to get it by way of work around,then it will actually ''brick'' your phone. this is a good phone, but the only option i have found that actually works is to use my pioneer z130 car stereo, which saves the contacts to the head unit itself and has its own voice dialing that does work. however, this is the only option.as a car stereo business owner and the holder of a masters degree in computer science,i have tried everything to make it work, but this pioneer stereo option was a fluke. so if you want to use bt for voice commands or voice dial period....by a different device,not a sensation.
