I hardly ever actually "talk" on my GA02 flash, so I haven't had a chance to experience/test the static (yay Skype).
But, I can say that GA02 is best performing radio flash I've ever had.
Nearly instant "signal locks" when I enable data, on both 3G and 4G. I'm like, "that really wasn't that fast, was it?" And then I get an email notification a second later. Background: I leave my data off almost exclusively for battery (days on a single charge) and just use WiFi. I only enable data when I need it, like tethering on the train. Or, when I get a baby picture MMS'd to me. Tap the DATA and BAM, I got 3G/4G connection to download the MMS.
Lot more 4G towers on the 110+ mile commute (220+ miles round trip daily), to NYC on the Hudson Valley Metro North. I'm constantly on 4G, until I get to the city (even the Bronx has 4G! Why the hell doesn't NYC?).
For comparison, last week I flashed back to FH05 to test it on the same commute. I barely saw 4G near Croton Harmon (1/2 way) for about 5m, and that was it. Also, I had to wait 5-15s for a signal lock every time I enabled data upstate, on the train, and in the city. I couldn't believe how bad it was.
Went back to GA02 while on the train yesterday, cause I wasn't getting a signal, and after a reboot, BAM I had 4G.
