The Notes app is pretty handy for jotting down notes on the go. If you have an iPhone 4S, you can even dictate them. And, now, you can also change the default font to one that’s easier to read for you (from the Notes screen). More importantly, if you have more than one email account that supports Notes, you can choose a default email account to sync your Notes with. This is handy when you want to create notes in one place (say your computer) and read them in another place (say your iPhone). Note: This may not be available on all carriers.
