We have 4 Teracubes. One of them will only use 3G data since the update. That phone has the exact same carrier and APN settings as the other phones. We have restarted, turned data on and off, removed and reinstalled SIM.
Also, all 4 have horrible GPS. It often shows us floating alongside the road we are on and doesn’t recognize turns quick enough, as such the verbal directions are useless. We have tried doing the ‘figure 8’ recalibration, but it doesn’t seem to do anything.
