I hope this is posted in the correct place..... I have a t-mobile g2 running 2.2 with the "use wireless networks" checked in the settings. When using an app that uses the network based location, it doesn't work. Location works fine when I use gps, wifi, and 2g network. But when I use only the network location on 4g network, it doesn't triangulate my location, and it never has. Very frustrating. I've searched everywhere for a solution, to no avail. Please help. Any ideas?
