Cincinnati Bell has announced the Ice Cream Sandwich update for the HTC Sensation starts rolling out today. Sensation owners will get updated to Android 4.0.3, but there's no word on what version of HTC Sense to expect. We're fairly certain it will be 3.6, just like the other Sensations received. The OTA starting today is expected to be completed by April 30. Cinci Bell also stresses that users will not have to visit a store, nor will they lose any data during the update. Interestingly, they also state that customers don't have to update their phones, which is in contrast to most carriers who require the latest official version for any technical support. Holler out if you see this one!
