Okay, so then you are probably under the misapprehension that this is the main driver for improvements.
For giggles, if only 10% of people with iphones report one error a week, calculate how many full time people it would require to process them.
In reality, their biggest problem is probably operator (IE people reading reports) time, not lack of error reports. I would take a massive data entry operation to handle them all.
If they are smart, they will have realized by now that relying on user reports to correct things is basically impossible, unless it's an automated system, which has it's own issues.
In short: If you think crowdsourcing is the way they will solve their data/data quality issues, you are probably wrong.
