Update
So I gave in and purchased this app. I went to the Giants game last night (AT&T has full coverage at the stadium), and streamed the game.
A quick set of review factoids from my first experience:
1 - Both audio feeds were available, home and away.
2 - Audio was only available right before 1st pitch, so no pre-game audio can be heard.
3 - Despite pefrect signal strength, the game did drop out a couple of times and when it did it took a bit to come back in.
4 - The clairty was perfect, just like a strong raido broadcast.
5 - The game delays is about 15 seconds, which was a bit annoying for watching the game live. It was always a play / pitch behind what was happening. TV and Radio at most have 5-7 second delays.
6 - The battery drain (screen off, just streaming radio) is very signifigant. My phone had a full charge in the morning, was not used all day, and was down to 10% or less battery after a very short game (2 hours, 8 minutes). A long game, or some phone use durring the day is going to mean a dead phone before the end of a game.
6.a - Subpoint to the battery drain, was the fact that you don't get the warning messages if you are not looking at the screen. As I just steamed the audio, I had no idea until late that my phone was set to die.
Otherwise, nice app. Ideally it could be improved by:
1 - improving battery drain
2 - improving connection to the audio, or quickly reconnecting after a drop
3 - allowing for more pre-game audio (even if its the 15 minute pregame show, as opposed to the KNBR pregame show).
