Google announced multiple improvements to Gmail for mobile today.
Multiple sign-in support To sign into an additional account, click on the account switcher at the bottom of the threadlist, then click "Sign into an another account." You can quickly switch between accounts by selecting the desired account from the Accounts menu.
Mobile-specific signature To create a mobile signature, from the menu view, press the new settings icon, choose your signature, and then check the box that tells us you want to activate it. If you ever want to disable the mobile signature, you can uncheck the box and we will use your desktop signature instead.
Vacation Auto-Responder You can now set your auto-reply using the mobile interface. Simply choose a start and end date and specify your message, just like on the desktop interface.
Separate Bookmarks As part of added multiple sign-in support, we've updated URLs so that each account can have a separate bookmark. For those who have previously bookmarked Gmail for Mobile, please update your bookmark.
Who cares? Are not most people here "apple heads" with mobile devices running ios? Do we not all then have a mail app which is able to access multiple gmail and other mail accounts simultaneously? This is only for other people with inferior devices, no? I have 4 gmail accounts and I've never gone to gmail.com on my iphone nor ipad.
