I love the Gmail iPhone app. In particular, I love that it lets me change the "from" address, similarly to how the gmail.com site lets me do that. Neither Mail.app nor Sparrow made it easy to change the from. I have a few different email addresses that all get forwarded to my gmail account. Finally my mobile mail problem -- being able to select my from -- is solved. If anyone from Google is reading this, thank you!
In Mail.app on iOS you just have to tap the 'From' address and choose a different one. What am I missing?
To send from a different 'From' in Mail.app, first you need to connect your iPhone to additional email accounts (Settings->Mail). Then these addresses will show up in your 'From' drop down.
But then you end up with multiple inboxes in your Mail.app. Which is messy, fills up storage, and hurts my brain -- since I never need to check my other inboxes (because all my email addresses forward to the same Gmail account).
With the Gmail iPhone app, I just need to prove once (in gmail.com) that I have access to whatever 'From' addresss I want. Then I can select them in the Gmail app.
Note: I admit that the viewport issues discussed in the blog post are indeed an annoyance that I hope Google fixes soon. But I prefer Gmail app to Mail.app nonetheless.
