Very unscientific test -
Using 1.04 I soft reset my Touch pro (on MetroPCS w/o EVDO) and went to
www.dslreports.com/mspeed and ran the 100k test 3 times and then the 1mb test 3 times.
D/L speeds were (100k) 106 kbs 119 107 (1mb) 116 133 117
Then I flashed the 1.07 radio (it soft resets after flash) and did the same thing
D/L speeds were (100k) 125 113 118 (1mb) 121 141 127
So this is just sitting at my desk at work (in San Francisco business district) and does not address battery life, ect, ect, ect.... but it is one thumbs up for the new radio.
