iPhone and iPhone 3G users have been waiting months for what will be made available today – the free upgrade to the iPhone 3.0 OS. 

Apple will reportedly deploy the update around 12:00PM CDT.  You will be able to upgrade your iPhone via iTunes once the software is made available (you will need iTunes 8.2 or above in order to install the update).

iPod touch users will also be able to update to 3.0, but the upgrade will cost “only” $9.95 plus tax.
