Answer 1

This is not exactly an answer as it seems like Home Screen apps in ios6 has some bug related to GeoLocation, but I found the following link very helpful. It explains that as Home Screen apps are now stored like native apps, they have their own storage/caching.

Geolocation works on the first iteration but fails to update from then on. the work around is to remove the following meta tag so that Home Screens app run in Browser mode (I am not sure if it is exactly call a Browser mode). The app will unfortunately render with the browser headers and footers, but GeoLocationwill be working again.

iOS 6 Geolocation and Local Data Storage

"Data in Home Screen apps are now stored like native apps. Native apps each have their own sandbox where their data is stored, backed up and restored to. Prior to iOS 6, Home Screen apps shared data with the same app running in the browser. If the user cleared the cache in the browser, the Home Screen version of the app would lose its data too.With iOS 6, Home Screen apps’ data gets saved to a sandbox just like native apps. Backups and restores handle the data properly, and clear cache in the browser will not affect them."
