Multiple from addresses

Hi Guyz

I have 2 email account setup in my iPhone5 (iOS 6.0.1)

Yahoo - Default yahoo

Gmail - Microsoft Exchange (since default Gmail option doesnt have Push option it has only Fetch function)

Now in my normal desktop version i have 2 from email setup for Gmail and 5 from email setup from my yahoo. Means for example if anyone send a mail to my gmail : abc@gmail.com in the desktop version i can reply from anoter from address def@gmail.com but in iPhone mail its not possible.

When I sync my Gmail account/ Yahoo on Mail.app I only get to send from the primary gmail/yahoo account. Is there a way to have all those accounts appear as a from option when sending?

I checked this tutorial : http://modernerd.com/post/535350679/solved-gmail-ipad-iphone-and-multiple-from

but that one is not for Microsoft exchange or yahoo, its for Other option

Can anyone share their ideas?
