All D810 versions have inbuilt GPS?

[RayEarth]

Hey guys!

I'm going to buy a few Dopod D810 (one for me, along with a number of my friends) from China/Taiwan. I was wondering if you guys know:

1. Do all D810s have inbuilt GPS?
2. Any differences between later or earlier D810s?
3. How do I check whether a D810 is the 'early' or 'later' editions?

Thanks in advance guys!

The gist is that
"Availability of GPS ROM Shipment of D810 arriving from March 2007 will have the GPS ROM installed into the devices. Existing D810 users can upgrade their sets for free, by downloading a GPS ROM Code, to equip their existing D810 with the GPS function at Dopod International’s website at www.dopodasia.com."
