don't know if this is really known to most of - I Just thought i'll make my post because i didn't any simple Information on this.
YES - Lenovo S10 with the 3G Card from Ericsson has got Built in GPS - and it work's like a Charm
In particular im talking about the 4329-A11(Austrian Version sold by Provider A1 with 5Gig HSDPA Package) and any other S10 with the Ericsson F3507g 3G Network Card.
Basicly all you have to do is get the newest Driver from the Driver Section in this Forum http://dl.getdropbox.com/u/1138738/S10%20Lenovo/Drivers/DriverFiles/XP/3G%20Driver/54gx06ww.exe
And you have to have at least ANY Sim Card inserted in the SIM-Slot to enable GPS functionallity
You can en/disable GPS in Wireless Manager <SHOW><GPS>

It reports as a Standard NMEA Receiver on COM-Port 6
Additionally i would suggest a little helping Program named GPSGate (google will help) - It takes the Input Signal and you can easily outpu the Signal zo any Device, Program and so on - Perfect
Just thought others than me could get excited about this Info - Now my S10 is really the eierlegendewolchmilchsau (Egg-layingWoolMilkPig)- as we like to say
