I was seeding last night, and waited as long as I could for the 500 to download the WAAS Iona file.  Finally I gave up on waiting, and just started seeding.  It took just about an hour before the file was available.

Is anyone else having this problem?  I have it locked on to 138 with 135 turned off.  There was between 11 and 12 satellites available to the system, but it was at around 9:00pm CST.
