Many of you have been anxiously awaiting the arrival of Sparrow for iPhone, myself included, so I'm excited to report that it's here! Sparrow is a popular mail client for the Mac that focuses on providing the perfect email experience. That experience is now available on your iPhone.
Sparrow is particularly great for Gmail users because it handles labels extremely well. You are not restricted to Gmail, though. Sparrow offers full iMAP support including Gmail, Google Apps, iCloud, Yahoo, AOL, Mobile Me and custom IMAP accounts. It does not support POP or Exchange accounts.
Some of the favorite features of Sparrow include using Facebook to assign avatars to your friends, ability to add attachments while composing a message, a very well designed pane navigation layout, pull to refresh, alias support, and custom signatures for each email account.
Unfortunately, Sparrow does not support push. Not by choice, however; Apple made them remove it. At least for now.
I've been using Sparrow for Mac over Apple's Mail client for over a month now and have been extremely happy with it. I'm very excited about Sparrow on my iPhone and even though I've only spent a moment with it, I'm already impressed. Without push, however, it may be hard for me to make the switch from the native Mail app. We'll see.
