hey all, i wanted to get some feedback from other thunderbold users here in SoCal. Ive had constant 4G issues with my GPS (even after update, won't connect to GPS on 4G within a couple minutes, I toggle to 3G connects quicker), and issues browsing the net. often times when on 4G the load bar will slow to a crawl and just won't load a page, if i switch to 3G it makes pretty quick work of it. sometimes 4G works fine but most the time it'll slow to a crawl then i'll have to maually toggle to 3G, anyone have any simular issues???
