[Geowanking] Background Location on iPhone

[John McKerrell]

A blog post I wrote on Saturday has been made obsolete by Apple's announcements yesterday. A lot of what I said in the post is still valid though, you can find the post here:

In the event they suggested that social networks would use cell positioning whereas a GPS/Sat Nav running in the background could use the full GPS. I'm guessing that this is actually just up to the developer, though might be partly enforced by the reviewers. I don't really see place based background check-ins working too well from cell-based locating, especially if you're inside a building. Wi-fi might work better assuming it's possible to use that. In my blog post I've mentioned using various methods to determine the best frequency to detect a location.

Any thoughts?
