From the article:
> I checked iOS setting/cellular and saw an uninstalled app used 700-800MB. I closed the settings and reopened it and it was 900MB. The uninstalled app[s] used 1.2GB data in less than 5-6 minutes…
It sounds like a reporting bug rather than a data consumption bug. I guess I'd like to know if they saw those same #s from their cellular company?
