If I have installed on my iphone the latest 3.0 leak (not the official) when the official one DOES come out, is it gna notify me that I need to update or is it gna say I already have 3.0?
It will probably have a different build number, even if it doesn't change. If it does have a different build number, then you will be notified to update. If it doesnt, then it is EXACTLY the same, and you wont need to update.
