Upon upgrading my iPod Touch to iOS 4, I found one little change that really bothered me. My usual email workflow on my mobile device is to check-off and delete emails that are unimportant (server notifications, newsletters, etc.) and delete them. I would then proceed to read the important ones.
Unfortunately, Apple decided it would be a good idea to change the “Delete” button to an “Archive” button for GMail accounts under iOS 4. I don’t really need to keep messages about my server’s recent five minutes of downtime for any length of time, so I thought this was kind of stupid.
I was able to find a fix, however. Open your settings and navigate to the “Mail, Contacts, Calendars” page. Tap on your GMail account. Then turn off the slider for “Archive Messages.”
I don’t mind the idea of an Archive option in the Mail app, but not to the exclusion of a Delete function. Some things just don’t need to be kept.
