Ok I live in Chicago, I have had all models of the iPhone with AT&T. I am trying to convince myself whether to get a 16GB with LTE or get refurbished iPad2 16GB with 3G and save $150. Honestly I am really debating to even get 3G/LTE option iPad in general as I have never had good internet results with tethering/cellular on train rides in and out of the city. I pay for mobile hotspot for my phone but when in a crunch it never comes through in the city. I figure this is when the most I would use the internet breaking the commute. Any Chicago people have good success with 3G/LTE coverage from AT&T in the city?
