AGPS is *not* disabling normal non-"A" operation of GPS (means there is no need for a paricular fallback scheme - GPS starts and operates in "fallback-mode" all the time, "A" just updates a few variables more quickly than the GPS-chip would do anyway, so the chip finds his channels/sats/fix. Even if we would write completely bogus info to the chip, it wouldn't be worse off than without AGPS and starting on default values. btw: It seems to me as if 3 minutes difference in time shouldn't make any trouble. cheers jOERG
