The latest iPhone OS 4.0 beta features a great new addition to iPhone Mail for GMail users: the ability to archive mail.
According to the good boys at 9to5Mac, it replaces the option to delete your GMail: just swipe on a message like usual and you now get the option to archive as opposed to delete.
I think replacing delete with archive on the iPhone makes a lot of sense. GMail, after all, has plenty of space, and the real reason to “delete” mail in Mail.app is to easily clear out the inbox. Sure, there’s going to be occasional moments when you’ll want to nuke an email from orbit in a fit of pique… but in those situations, you can still just log into GMail through Mobile Safari to carry out the vaporization. This change prevents people from accidentally deleting important mails. Well done, Apple!.
