iPhone: Popular email app Sparrow, which happens to be one of our favourite email apps, is on sale for a mere 99c for the next two days.
While Sparrow still lacks push notification support for email (which you can fix if you're jailbroken), it did just add in support for POP email. The sale runs today and tomorrow before bumping up to $1.99 and then back to its full price of $2.99 by the weekend. If you're not a big fan of the iPhone's default mail client ,or you just want to check out something new, then now's the time to grab it.
