I have had gmail on my iphone for a while now, what i did was setup 'add new account>gmail' (e.g. firstname.lastname@example.org) for emails, then 'add new account>exchange' for gmail contacts and calendar sync. But now I have setup another exchange email account of my work email address (e.g. email@example.com) 'add new account>exchange'. It grabs emails in my inbox fine, but when I send an email, it keeps using my gmail address as the from address!! i.e. I open firstname.lastname@example.org inbox, hit reply, and it replies with email@example.com??? When I try to select a different from address it only gives me the option of TWO firstname.lastname@example.org choices... I tried searching around on google but nothing came up, maybe Im just using the wrong search string, but this is really frustrating. Any help would be greatly appreciated. Thanks!!
