per Jeff Diamond's suggestion, I am posting how to tell you are on a T3.
(we both had trouble finding this information, one of my coworkers found it
on the plugged-in site)
1. Check the company ID
FtrGet(sysFtrCreator, sysFtrNumOEMCompanyID, &companyID);
2. Check the device ID
FtrGet(sysFtrCreator, sysFtrNumOEMDeviceID, &deviceID);
3. Compare to the following matrix:
Product Device ID Company ID
Tungsten|T 'Frg1' 'Palm'
Tungsten|T2 'Frg2' 'Palm'
Tungsten|W 'atcl' 'palm'
Tungsten|C 'MT64' 'palm'
Zire 71 'Zpth' 'Palm'
Zire 'Cubs' 'Palm'
Zire 21 'Zi21' 'Palm'
Tungsten|E 'Cct1' 'Palm'
Tungsten|T3 'Arz1' 'Palm'
