well i finally took my dx to verizon because of the gps problem i had. i gots some advice from you guys on here (thanks!) but nothing worked. day 1. took it to the store and told them my problem, will not find location, if it does its really slow like maybe even an hour, and it would show my location several hundred miles from where i was. so their tech guy messed with it and come back about 10 minutes later and said it was all done. he said not to have all three location settings selected. only have the gps selected when using gps. the other 2 setting, "use wireless networks" and "enable assisted gps", was for everything else like "poynt", "where", weather apps, etc. the reasoning he said was that having all 3 selected made the phone confused on which location setting to use. i thought BS! but it worked at the time. day 2. next day it was doing the same thing! so i took it back in. their super tech guy wasnt there and the women didnt know anything about how gps works so they ordered me another phone. supposed to be in within a day or so. so the gps tip is if your gps isnt getting your exact location you mite try to just have the gps only setting on instead of all 3. hope this helps someone!
