So I've installed a 4.3 ROM and shortly after that (maybe a week) my data is nonexistent... 3G gone, 4G no where. I ended up talking to Verizon's tech and I did the "pull batt, pull SIM card, check all settings" song and dance. He eventually said he boosted the signal on my phone? When powered back on I had data for about 45 minutes and now nothing for the past few hours. Is anyone else having or had this problem?
