This is an utter farce. Before and after tests using a dock so the phone didn't move even a cm. Same test server. You all can believe what you want, but there's no logic to the carrier file giving you bars where bars don't exist, not "boosting" the amount of signal received. I laugh at the comments "it increased the signal" ... apparently the hack has a way to tap into ATT's transmission tower and crank up the power. LOL
I guess it's like arguing with someone who says the bible is real and god exists. There's no amount of logic you can throw that'll disprove them if they believe.
Maybe in some markets the carrier file is limiting speeds, but certainly not here in the SF Bay area. This carrier hack does absolutely NOTHING here except modify the ability to change the voice\data to 2G 4G LTE, etc.
didnt work for you i see, not everyone sees difference. but go ahead, throw some logic at us.
i for one saw a change in my stuff and no expense to the everyday use of my iphone, so why not i thought. then i just shared with others.
