I've heard that although in MTK-based receivers GPS signal is usually acquired from more satellites and with better HDOP than in case of SIRF III, the difference between speed and heading showed by receiver differs quite much from reality, and that MTK receivers aren't still good for pedestrian use. I wonder if it's all true for I-Blue 737A+
