A couple of weeks ago, I wrote about “Growl, a notification system for OS X.”:http://blog.smalldog.com/kibbles/?c=kb629  While some of you may have mixed feelings about Growl (I hear you, Mac!), there’s a growing number of people who want to get more out of the push notification technology on their mobile devices.
“Prowl”:http://prowl.weks.net/ is a companion to Growl for the iPhone or iPod touch.  Arguably, Prowl is more useful than Growl because people who really care about these notifications want them on the go!
An overview of Prowl’s features:
*Infinitely extensible*
Prowl is as expandable as Growl is.
*Push notifications*
As soon as a Growl notification pops up on your computer, Prowl will forward it to your iPhone or iPod touch over the push notification service found in iPhone OS 3.0.
*Simple, elegant list*
Prowl provides a clean list of all the Growl notifications sent to it from your computer.
*Easily send links to your iPhone*
Whether you need to call a phone number or visit a website, Prowl will link the notifications it displays inside the Growl notifications.
*Customized display of notifications*
Prowl’s Growl plugin can be configured to only send the most important notifications to your iPhone, or any level which you want.
To make everything work, you’ll need to register on the Prowl server. Then, you’ll need to allow push notifications on your iPhone (if you haven’t already).  
Some of the best things about Prowl are the preference settings. You have a lot of control over what messages you’ll see popping up on your phone, and one of the most useful features is that you’re able to set a priority for your notifications.  
That way, you can avoid seeing messages any less important than “emergency” if you so choose (Prowl will only send notifications that have “at minimum the priority you’ve chosen”).  
Prowl is free and works with Growl-compatible operating systems: Mac OS X (10.4+) and Windows (using Growl for Windows or Snarl).
