Apps with push notifications
I couldn't see anywhere with a list of apps that have push (although it may be hidden somewhere) and it might be useful to have a list of those that have this feature.
I've got Remember The Milk which has just got push notifications and I've finally got it working after firing up the desktop app (instructions are very absent so it took me a while to sort this out!). Ok, it does double up on some of the functions of the native diary but it synchs without having to connect to iTunes (big bonus) and I can tag events, create unlimited lists, use location services etc.
The only app I've got with push is Tap Tap 2 and the chances of getting any notifications with that are pretty much zero! Feel free to add your apps that have push to this thread.
