I would like to know how many iOS 3.2 (and presumably below) users are accessing my website. The reason is because iOS 3.2 had a maximum cache limit of around 25.6k, and files larger than this size would not be cached. This is according to http://www.yuiblog.com/blog/2010/06/28/mobile-browser-cache-limits/
We use both awstats and Google Analytics. Unfortunately neither gives the iOS version. awstats simply reports Mac OS X and the Safari version. Google Analytics does not report the version of the operating system either, but gives the Safari versions in great refinement.
A solution to this question would be a mapping of which Safari versions indicated iOS 3.2, or simply which Safari versions had the 25.6k cache limit.
