What will happen to iOS 5 GM release when iOS 5 will officially be launched today, I have installed iOS 5 GM release on my iPhone 4, from a download off the internet. it was an ispw file. Will iTunes ask me again to install the update, can anyone help? Also, the build on my iOS5 GM is (9A334) will this number be different on the "Official Launch version"? -I just don't want an issue on my phone if i need to bring it to Apple and they see that and ask questions.
