So I didn't even think twice when it offered a carrier update for AT&T... boy do I regret it, wow. So before I'd get LTE in my condo, then keep it into the elevator and into the parking garage and to my car, and usually back in the corner by my car it'd drop to 4G then when I pulled out of the garage it'd go back to LTE. Now I leave my unit, it turns to 4G... in the elevator, 4G... in the parking garage, 4G... and then it takes 2-3 minutes when out on the street to go back to LTE. Whatever thresholds they set, I can't take it. Absurd! My whole motivation for staying with ATT is their stronghold over TMO on LTE... but if I'm going to be sitting on 4G often, I might as well sit on TMO's 4x faster HSPA+ network. Anyone else notice this yet? I didn't notice it until I got out of my place and off the wifi. Talk about backwards progress. Ughhhhhhhhhh EDIT: to test it, I took my iPhone 5S (same model) that is still jailbroken and on 7.1.2, and walked side by side. Yep, the carrier update definitely broke the LTE in my building.
