This whole 7.8 rollout has been handled poorly. I doubt my device ATT HTC Surround will get the update. Twitter support and phone calls to HTC and ATT have yielded nothing. Microsoft does not do thier update grid anymore nor did they announce what devices are getting the update.
Letting Carriers into the update process screws everything up. Its very dissapointing. I still have not gotten the previous fix dissapering keyboard fix and was hoping to get WP 7.8.
