I keep hearing about how iphone users should update their firmware to version 3.0.1. I have an ipod Touch. Knowing that the update fixes mainly the sms problem with the iphone recently I wondered if it applied to ipod touches too. On trying to update it via itunes, I click on 'Check for Update' and it says mine is up to date on version 3.0 - is this correct or should I be able to update to 3.0.1? Thanks.
