Been wondering exactly which data service is replacing Google as Apple's map provider? According to these leaked screenshots (shown above) from the iOS 6 developer beta running on an iPhone 4S, it appears to be TomTom. The company is no stranger to iOS, as its navigation app and car kit have been available on the iPhone since 2009. On an interesting note, the maps application specifically mentions "data from TomTom, others," which means there may be other suppliers that aren't getting called out by name. We'll keep you posted as we hear more what's going on behind-the-scenes.
Update: TomTom has independently confirmed to us that it indeed "has signed a global agreement with Apple for maps and related information."
