If your download fully cancels in the middle, do not resume the download. When you try to resume - the phone will think you want to resume installation [it thinks the download is complete] and will update the phone with the partial firmware download. For those phones that were bricked, that is what was said happened to them - myself included. Now, why would the update not realize the firmware isn't complete and just abort the update is beyond me. Many of us ended up with paperweights from that. Had to go to AT&T to replace the phone last night.
