I upgraded to iOS6 to get the turn-by-turn navigation. Now I discover that only iPhone 4S and 5 devices get voice guidance. There is no way I can get Google Maps back without jailbreaking my phone.

The voice limitation appears to be simply planned obsolescence; Waze can handle it without issues. This is a slap in the face to someone who paid a lot of money to Apple for a current-generation phone a little over a year ago.

Apple's closed platform has worked only because they've been able to give consumers such a high-quality experience. I think this fiasco will be a big wake-up call to lots of iPhone owners about how Apple's limitations can hurt them.
