I have just received my 7100g for Cingular and have been researching around here for a few days but still have a question regarding the GPS options. I have compiled the following list of services offered at this time but I am not sure that which would be a better option:
Spot for BlackBerry
Nav4All
trackem.com
mapquest navigator- does not offer Cingular only Verizon and Sprint
GPS Track (GPS TRACK)
Needless to say I would prefer a free service so any help would be appreciated.
