Your results will likely depend on your local service coverage. In my office I have marginal Sprint coverage. With the stock Sprint radio (1.03) I had 1 to 2 bars at most places in my office, with a couple of dead spots. I flashed to the Sprint 1.11 radio yesterday and had fewer bars everywhere, including a major dead spot right at my desk
. I then flashed to the Telus radio and now have an average of 1 bar better coverage everywhere. YMMV.
