One reason Gmail for iOS still sucks 
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!
