Okay, here are almost all of the screens available on the iPhone 5's Field Test function. All of these were taken at one time just at the foot of the Trophy Club, TX water tower, right behind Sabre HQ off of TX-114. IMO, this is a strange location for a tower, as Sprint also has a 300 ft tower less than 2000 ft away. My assumption is that this one is designed to serve Westlake's Solana complex just across 114 -- but I can say that I can't get LTE over there. I ran SpeedTest, RootMetrics and Sensorly -- quite a variation, but all were fast: Test Date: Sep 24, 2012 1:58 PM Connection Type: Cellular Server: Fort Worth, TX Download: 8.31 Mbps Upload: 8.91 Mbps Ping: 177 ms External IP: 66.87.97.6 Internal IP: 30.120.181.6 Latitude: 32.9863 Longitude: -97.1672 (The field test images will follow later in this thread).

Here are some Speed Test results from the only LTE I've found so far -- a very tiny patch of Westlake, TX: Test Date: Sep 23, 2012 1:25 PM Connection Type: Cellular Server: Fort Worth, TX Download: 7.99 Mbps Upload: 7.50 Mbps Ping: 177 ms External IP: 66.87.97.145 (spcsdns.net) Latitude: 32.9808 Longitude: -97.1716

I thought you would appreciate these LTE Field Test screenshots.

When I find an AT&T phone, I'll give it a go. Or maybe I will trim one of my existing SIMs. I would like to see that it's unlocked as well, but my understanding is that Sprint will unlock the phone for international travel on request? Sent from my iPhone using Tapatalk

So, the answer is that you can make a call. You can't see signal strength bars (says No SIM), but you can make calls. Also tried field test and that worked, too.

The iPhone 5 contains a SIM with a Sprint logo. If it's ejected you get a "no SIM" warning and it appears the radios disconnect from the network.
