Can i buy reasonably priced 3g usb modem/ datacard/ dongle/ stick having gps (hardware) functionality. Especially any of those by huawei or zte, as the dongles of these 2 companies are mostly compatible with the tablet. One that I did come accross is a dongle by at and t in USA which also comes with GPS functionality. Very pricey though. Will appreciate if others could share their views/experience here.
