The speed test app isn't updated
I can already see that some apps will never be updated.
Seriously when most apps aren't updated before the newer phone is going to come out, Apple will definitely have fragmentation going on.
Checking the US App Store from iPhone 4S, last update was Nov 2011...
And it says iPhone 5 support coming soon
I use Alien Blue for Reddit, it's a great alternative.
apple should force these companies to release updates for the iPhone 5.
if you're submitting a new version of an app, it has to have iPhone 5 support.
