tobeychris,
I have the TP and Diamond Now. They both seem to not be using the agps the same way the 6800/titan/mogul did. On the 6800, It would initiate a data connection the instant i pressed, 'use gps' in google maps. the only time it wouldnt do this is when i had just recently used the gps, so the phone knew the gps data was still good for the time being. here what i would do, load up google maps, let it use the data connection to load the map data, then DISABLE the data connection. wait a moment then click use gps. before the map would load a new image or anything, bam... it would initiate a data connection to download the agps data from the PDE server. On the Tp and Diamond this does not happen. at least for me. im using might rom4 on both devices. do u know anything about this, can u test it out. thx. i noticed on the TP, compared to the 6800, the intermedate gps drvier is different and some reg entries are different.
heres my old thread but the titan gps.
