I am looking at this WWAN modem. The site is in Hungarian, but the specs are not. It lists GPRS among its capabilities.
Will this give me an in-built GPS for my laptop? If so, will it be very problematic? Will it drain my battery more or can I turn it on and off? Do I need extra drivers for it?
Mine has a built in WWAN (4299PG) and the GPS function already works. It is possible to turn off the WWAN device. You can get the drivers via the Thinkvantage System Update.
