T-Mobile is jumping on the bandwagon of carriers that promise Android 4.0 Ice Cream Sandwich updates for their existing phones but don’t say exactly when we will see them. The carrier has posted information to its support site saying that the HTC Sensation 4G and the HTC Amaze 4G will both see Android 4.0 updates in the future. Unfortunately, we don’t know exactly when in the future that will be. HTC has been one of the most aggressive Android manufacturers with deploying Android 4.0 updates to its existing lineup, and it has already released a number of updates for international models and has updated the HTC Vivid for AT&T. Hopefully it won’t be too long before T-Mobile customers get invited to the party.
