We've expressed concern before that, with the arrival of Push Notification, the iPhone's built in alert system, especially the modal text boxes, may not be a user-friendly solution. There have been a couple creative solutions to this problem already on the Jailbreak side, but GriP takes a rather novel approach: it aims to be Growl (the well known Mac OS X global notification system - Wikipedia link) for iPhone -- hence the name.

There's a users and developers guide hosted up on Google Code and iphoneblog.de posted the video embedded above to give you a sense of how it works.

Personally, I've always found Growl to be a little "floating" for my tastes and preferred what looks like more "grounded" approaches in Google Android and especially Palm Pre, but hands down anything at this point might be better than Apple's built in version.
