I’ve been a long time user of Gmail and always loved every second of it. It has always beat the crap out of any other email service I’ve tried. I have had one slight pet peeve though, and it was something I ran into as soon as I got my iPhone. Before then, I only ever used desktops and so the problem was non existent. I have used Gmail’s feature of connecting other email accounts to my main Gmail one, therefore having a unified inbox (no need to log on to several different accounts) yet still being able to send messages from different addresses.
Up until now I have been unable to do this on my iPhone, and my new iPad. That is, until just now when I stumbled upon Nick Cernis’s excellent guide, the aptly named Solved: Gmail, iPad, iPhone, and multiple from addresses. It works like a charm.
