I'm not entirely sure why this is a big deal right now. I had an iPhone 1 and when the App Store opened up I downloaded Cube Runner. The accelerometer calibration was off by A LOT. Just keeping my phone flat on the table would cause the ship to shoot off far to the left.
I actually had to replace my iPhone at the Genius Bar (I think more than once) in order to get one that worked better.
Since that was over 5 years ago it is very unlikely that Apple will now decide to offer software calibration in the OS.

I am pretty sure iOS 7 already did that.
