Sparrow [iTunes $2.99] is proving to be a very popular email client for the iPhone save for one very important piece. Apple rescinded the App’s ability to do push notifications prior to its public release meaning that it is effectively neutered for real time messaging. That’s a bummer for the otherwise impressive Mail client. All hope is not lost however.
If you Sparrow lovers were looking for a reason to jailbreak, you now have one. IpuIpu has your Sparrow Push notifications right here:
iPhone Jailbreak tweak for the popular iPhone app Sparrow, which enables eMail push notification when the app is in the background making Sparrow a real replacement for the stock Mail application.
It also makes an effort not to drain your battery:
Sparrow Push uses a very efficient implementation using the same APIs that VoIP apps like Skype use. Since there is an additional, permanent internet connection and Sparrow becomes active everytime there is activity in the email account, there will be a higher battery usage, but it should be comparable to what Apple Mail’s exchange push implementation is.
