Access both Hotmail and Gmail from iPhone
The built-in Mail app on iOS is able to show both your Hotmail and GMail accounts. To see both of them you can either switch between them by pressing the back arrow and then choose the other mailbox or you can use the view "All Inboxes" instead where you will be able to see e-mails from both accounts in the same view. If you enter a view, the Mail application will remember which one you used and will open with that one when you launch it next time.
