Congratulations Matt! Our good friend at Exploremetro has managed to get a million people to download his iPhone app - and he's decided to celebrate by giving it out for free! Just for the next two days though. In case you own an iPhone and were on the fence about picking this up, now's the time to give it a twirl. You would have to empty your pockets of 99 cents otherwise! more ›

File this under things that can come in handy: Exploremetro (who's intrepid founder became - we think - the first person to visit every station on the Shanghai Metro system in one day earlier this year), has an iPhone app out that details Shanghai's underground. Besides having up-to-date info on line extentions (and free updates when the other lines are finished), the app also allows you to plan routes, communicate bilingually and access the map without internet. Fun! more ›
