In Short

Mail is one of the core apps of the iPhone, iPod touch, and iPad. Rich, HTML email was shown off by Steve Jobs in 2007 when he first introduced the iPhone, and again in 2010 when he introduced the iPad. It was and is so important, he put it in the iPhone and iPad Dock, and by default there it still remains. Whether you use the free iCloud account that comes with your Apple device, or Yahoo!, Google's Gmail, Microsoft's Hotmail, Live, or, your local ISP email or something else entirely, whether you have an IMAP, ActiveSync, or POP account, your iPhone, iPod touch, or iPad can keep you connected to it wherever you go, and whatever you're doing.
