This is another very basic tip for iOS 4.2 users on the iPad – so if you’re a savvy veteran user it’s best to move along now.
One of the nice smaller features we gained with the 4.2 software update is the ability to change the font in the built-in Notes app. Doing so is super easy as long as you know where to go.
You cannot make the change within the app itself. You just need to go to the Settings app, and tap on Notes in the sections pane on the left (just below Photos and above Store). Once you do, you’ll see the three current font choices shown in the right pane. Just tap on
Helvetica your preferred font and you’re good to go.
