Too many steps to switch email accounts.
I find navigating between the four email accounts I have on my iPhone tiresome; I have to click-click-click dozens of times a day to see what’s in each mail account.
One common suggestion is to consolidate all your email accounts into one master account, like gmail. But, for a number of reasons, that won’t work for my situation.

This will save dozens of clicks a day.
Therefore, I humbly offer my solution to this problem: change the account name at the top of each mail screen into a pulldown menu.
Problem solved. Now where do I collect my fee?
Or just do what Gmail does, have them go into 1 inbox and label each email from which email address it came to. When you hit reply, it gets sent from that same email account. Though even in that situation, a pull down would be a nice convenience to isolate one email account at a time.
Excellent thought, Jasen, though I do like the fact that the iPhone mail app keeps emails from separate accounts in their own folders. Perhaps this is an option: show accounts separately or merge accounts.
Nonetheless, in the show accounts separately option, I’d still like a much quicker way to navigate between accounts.
Overall, the iphone is amazing. But your example exposes the single biggest usability issue with it: sibling navigation. All the navigation is camel backing up and down, almost none (aside from the double button push) allows you to move horizontally — such as among the accounts. This is even more frustrating when you are in an app. While do I need to see all the apps in order to select another one?
I was JUST thinking about this usability issue the other day and researched apps, I assumed that you could put app (buttons) for each account on the home page, but I haven’t been able to find that either.
