This may be a stupid question, but I can't figure out how to upgrade.
There is a link on macrumors.com but I would advise waiting till its "officially" released there have been some issues
So then everyone I have seen posting about the new apps downloaded the pre-release leak?
no its from the apple servers but there have been bug issues and stuff search the iPhone forums u will see all about it
