FWIW - from a response by Samsung Service on Facebook yesterday:
We understand you are frustrated and we are listening. Samsung feels it is important to make the Android 2.2/Froyo upgrade available only after we feel that we can give the millions of U.S. Galaxy S owners a simple and reliable upgrade experience. Due to the complexity and unique functionality of each Galaxy S device, we are performing additional testing and are working to make the Android 2.2/Froyo upgrade available to all Galaxy S owners, ASAP.
Thanks for your cooperation and patience.
