For Google Maps, Advanced Forward Link Trilateration (AFLT) works fine on the Sprint version. This is not aGPS/GPS but cell tower triangulation and it works instantly and accuratley on the Touch Pro 2, Snap, Treo Pro and Intrepid. I have never seen AFLT work on CDMA and Bing though. Must have to do with the API & Sprint.
As others have mentioned, the weather/GPS thing is coming with Manilla 2.5+ and may be in our WM6.5 update.
Add caller is not there b/c CDMA conference calls are limited to 3 parties.
At least our weather shows up in the calendar, unlike AT&Ts , we have 3.5mm jack and world-phone ability (CDMA + GSM)
