If you're like me, you'll thrash your smartphone for e-mail, and if you're an iPhone user, this news might make you happy. Popular e-mail client, Sparrow, has been released for the iPhone.

The iPhone app is just $3, and brings the formerly Mac-only app into the iPhone world. It drags along the pane navigation from apps like Facebook and Twitter, swipes bring in the main navigation for folders and labels, as well as quick shortcuts to deal with individual messages.

Simplification is the message here, though, where Sparrow has features that Apple left out of their mail client. Contacts and messages can sort by priority, users can mark all messages as read, and users' profiles feature prominently. You can also attached photos directly from within Sparrow, solving a problem with Mail that required you to go to the photo library first.

Sparrow works on any iOS device running 5.0 or later, and supports just IMAP mail accounts such as Gmail, iCloud or Yahoo. At the moment, it's not clear whether POP3 accounts will get support, but for a decently featured mail client, I see that coming in a future revision.
