I called at&t to get insurance on my captivate. While I had the rep on the phone he told me he owned a captivate. I asked him why my phone couldnt communicate with the at&t update servers and this all started after the last gps update! What he told me I'm not sure I believe. He said that at&t didn't support froyo 2.2 because of tethering and the update servers are blocking the download of froyo until they can take out the tethering option! I did'nt even ask him about froyo just about the communication error! I asked him if at&t would support froyo once the tethering is removed he said yes but did'nt know when that would be! This all sounds suspect to me!
