Do you have to use xcode and set your phone as "use for development"? I am trying to install ios 5 on my iphone 4 and whenever it tries to install it says there was an error.
Just signed up to be a developer two days ago for ios 5
No, you don't need Xcode. Just download the beta, install iTunes 5 and install iOS 5 beta 1 by clicking on the Restore button by pressing the Alt key simultaneously. You will be prompted to select a file to upload. Select the beta you just downloaded and you are good to go. Of course you need to register your devices UDID before installation. You can do that in the developer portal.
