This fall will iCloud allow us to download all previously purchased apps? Or only ones recently purchased with the latest version of iOS w/ iCloud?
You can ALREADY do this. This is a feature they've already put out there if you have the most recent version of iOS 4.
Go to SETTINGS > STORE and check that it's logged in correctly. Give it a second, the system has to enable that feature while you're on that screen. Then go to the 'updates' section of the app store on the phone and you'll see a 'purchased' bar on the top. Click that to see everything you've ever bought, ready to re-download.
Thanks for the quick response. Are you using an AT&T or Verizon iPhone 4? I'm not sure there is much of a difference between the two when it comes to the firmware updates (I'm using a VZW iPhone 4), but I did what you said and nothing is in my updates tab saying purchased in the App Store. I know this is in the iTunes App that I may re-download purchased music but not for apps.
I'm on AT&T, so if anyone else has a Verizon phone that knows about this comes in, that might be who can help you. I'm not sure.
I don't know if you are trying to avoid using a computer, but you could download previously purchased apps in iTunes and then sync them to your phone.
