Hey guys. here is my short term experience with the radios. Went through the newest radios from each of the providers listed.
Telus. Great signal in my house. Voice call sounded clearer than stock sprint. My biggest issue has been with listening to sx2 radio and getting texts with my original radio and this radio did the same thing though not as often. My issue is when listening to sx2 and I get a text it goes out of evdo to 1x and won't go back to evdo until i actually stop the stream of music and wait for it to go back to evdo...very annoying.
US cellular. Worse for me in all categories. I am in north houston, your results will vary.
Verizon. Signal is interestingly 1-2 bars less but the voice signal is the clearest. Gps aquisition is almost instant in my house where sprint would take over 2 minutes to lock. The best part is that when listening to sx2 it rarely goes to 1x when I get a text message and that is awesome. I have no idea on battery life but I presuming all this goody goodness with a weaker signal is going to result in some major battery drain. Will report back on battery in a couple of days. I also might put telus on my wifes TP2 to compare the two. Yes we're gay like that, we also dress alike and drive the same brand of cars.
Again as anyone will say on this forum these results are very subjective so don't expect the same on your phone. You need to try them on your own phone in your area to get accurate results...not sure why I wrote this afterall. Oh well
