My 3G was doing fine (was better before the FD02 upgrade, but still okay) until 2 days ago, I installed and used FoxFi to download a 145 MB upgrade for one of my other WiFi-only phones. Now here at the office (4G WiMAX is good on WiMAX phones, 3G is also usually very good), 3G has started to suck and drain battery. I have also noticed weird spamming text messages from 8737. Anyone got any ideas? I don't think it's the radio as it was fine until I installed FoxFi (from their website instructions).
