As usual thanks to Engadget I am now aware that the iPhone 4.0.1 and the iPad 3.2.1 updates are available through iTunes. These updates don’t do much, just fix the formulas for displaying signal level, however a lot of my friends have been having problems with 4.0 so maybe this will fix things. If you haven’t upgraded already connect your iPhone/iPad to iTunes and click on the Check for update button. I guess they released this just in time for tomorrow’s press conference!
