Details About Downloading IOS 7 On The IPhone 5?

I just recently purchased my new IPhone 5 about 3 weeks ago. I was hoping that it would come with IOS 7 already downloaded onto it or have the software update pop up after a few days. This hasn't been the case and I'm curious as to how I can get IOS 7 on my IPhone 5

You can download IOS7 Beta3 straightly in your iphone5.
This version is quietly stable and few bugs.

Are you seriously think that when iOS 7 is still in beta that it would come in as in full version? What a joke, only if you pay as a developer to make apps and such from developer.apple.com you will auto update message for iOS 7.

Right now there's iOS 7 Beta 5 and possible Beta 6 by next Monday or Tuesday before the Final Golden Master waiting to be released. Beta 3 is old.

And there's some things for you to consider to wait,
-September 10, 2013 iOS newer Version every year since I know from iOS 6 maybe 5 but 5 made 8 Betas.
-Your apps won't work till they are updated to iOS 7, only a few have been updated to work up to beta 5

Update now and your 85% of your apps will constantly will crash and the developers will not update right away until the golden master is release before the public release to the world so in the time between GM & release date, developers will have time to update there apps, some apps will may take longer to update since the different UI Changes.

Just wait 1 more month.
