One of my favourite iPhone apps has gotten a major update today to 4.0. Tube Deluxe which lets you check the state of the London Underground network for delays, problems and closure of all lines. Tube Deluxe 4.0 brings with it push notification which allows you to get real time push updates on the state of the tube. It allows you to conveniently limit the alerts to certain lines and to certain times of the day so that you’re not pestered with updates.

Tube Deluxe 4.0 which is only £0.59 to new customers is a free update for existing customers and is currently available in the App Store.
