In my opinion, Sparrow is the best iOS mail client, even better than the native mail.app found installed on iOS 5. Using Sparrow, you can better organize your email account, whether you are using GMail, Yahoo Mail, hotmail, or most any other email provider. The great thing about this is that setting up new email accounts is very easy.
After you add your account, you can then have quick access to all of your labeled mail and mail that you put in specific folders. This is a really nice feature as you can really effectively sift through emails. Made by ToolgyTV. Visit http://toolgy.com for more.
