If you don’t want to wait for the official release of Apple’s newest firmware you can install it now. Normally you will have to make sure that your UDID is registered with Apple before you can actually do this. Unlike the beta versions the GM can be installed without this. Here’s what you’ll need to do…
-You must be using iTunes 10.5 beta 7 or later. Just google search it to find it.
-Then download iOS 5 GM. Google search this as well. Save it to your desktop to easily find it.
install and run iTunes first, then after you plugin your iPhone hold down the shift key and iTunes will let you choose where to install the iOS 5 ispw file from where you saved it.
DO NOT INSTALL ANY PREVIOUS IOS BETA FIRMWARE! This will brick your Device.
If you are familiar with how to do this and you just can’t wait till the 12th here is your chance to jump on board.
