Then, that's not turn-by-turn. It's just the old style directions that are in every previous iOS

The old style does not update automatically based on gps position, it requires you to press the next arrow yourself. iOS6 will change it to where it will change the onscreen direction to the next one you need automatically based on your gps location, so that is turn by turn directions.

On my vehicle navigation I run without sound on my turn by turn, so the iP4 will perform very similar to it. To me, the constant "turn right ahead" is annoying as h3ll.
 
I think you can guarantee iOS 7 on the iPhone 4- with stripped down features of course. That's what happened with the 3GS.

The iPhone 4 is now currently sold for $0 under a 2-years agreement with carrier. Which means, support for the device must still go on for Apple. If Apple is willing to sell the iPhone 4, they are obliged to provide support although the iPhone 4 is a 2010 device.
So which means, as long as Apple decides to continue selling it, it is obliged to continue supporting it as there will always be people who would opt for it anyway .
 
I'm still using my 1st gen iPhone as a Boxee remote and alarm clock. I guess it's up to the individual how much use they get out of older phones, since it's just a question of how many of the more advanced, newer features you're willing to do without before you're compelled to switch.
 
My iPhone 4 is on its last legs, but with a little TLC could be restored to a great device. I plan on making it a little project of mine once I have my 5. My camera lens cover is completely scratched up, making the camera useless. The home button is also failing and needs replacing. I plan to buy a new back plate and home button, make the repairs, replace the battery, reformat it clean with iOS6, and then maybe give it to my dad for him to use as his first iPhone.

Great idea! Makes me wish I still had my 2nd gen iPod touch around. I lost it on vacation a few years ago :(
 
I'm going to keep using my iPhone 4 for international travel with a prepaid local SIM card. Plus, I figure I'll need a break from Android from time to time (replaced it with a Galaxy S3).
