Since your in tampa your 4G runs on AWS(2100/1700) and voice runs on PCS(1900) so it would always show your PCS(1900) signal in the signal bars but i didnt know that change in ICS
It's hard to find any information on the details of how the signal and data implementation change in 4.0.
This was taken from a post I found and kinda explains it better than I did.
"From what I've read, the ability to properly display the LTE signal strength was not supported in Android until Android 4.0 Ice Cream Sandwich (though this could be inaccurate). I do know for sure that earlier Verizon phones (such as the Thunderbolt) deceivingly displayed "4G LTE," but then displayed the 1XRTT signal strength. That's why occasionally as you traveled out of an LTE coverage area, you would have 4/full bars, and then suddenly drop to 3G. In actuality, you were dropping below -120 dBM of LTE signal, and were near a tower that had voice/3G on it, but no 4G. The Thunderbolt to this day still displays the signal in the same way. I'm not sure if the recent Android 4.0 leak for it has changed this functionality.
The first phone to display LTE signal strength correctly was the Galaxy Nexus. The LTE bars displayed
are in fact representative of LTE signal strength, and not 1XRTT/Voice. I know that Motorola's Blur UI on the RAZR models added an extra screen to the system information page that displays (separately) 1XRTT and 4G LTE signal strength (the actual dBm values, rather than a signal bar visual), so I believe that the RAZR and RAZR MAXX both display 4G LTE signal accurately. As for any other phones, I don't have personal experience with them, so I could not say for certain.
So, basically, to answer your question: It depends on what phone and what version of Android you are running. "
And another post
"It really depends on the phone and OS you're running. For example, in Android 4.0 or later, the phone will display the signal level of the connected network in your case LTE. Along with that now it properly displays LTE accurate measurement RSRP (Reference Signal Received Power)which tends to be about 20dBm lower than the usual RSSI (Received Signal Strength Indicator).
For example, my old HTC Thunderbolt used to display RSSI out of EV-DO nonstop, even when I was on LTE. With Galaxy Nexus we started to see RSRP values and people started freaking out how the reception sucked. Now with the likes of Galaxy S3 and the bulit in ServiceModeApp.apk we can properly measure RSRP and RSRQ straight out of the baseband, which completely matches the notification bar indicator.
Hope this helps. "
Maybe I'll be that lucky too.
