Space is not the issue. The a-gps offline donwload the almanac, which is valid for 2 hours or so. And then predicts the position of the satellites for the next 28 day. Don't ask me why its 28 Most probably becaus 28 by 1.5 is forty-two.

Has anyone tried to tingle our beloved company to open up their marketed "oh-so-open" device hw?
