SG Buses is probably one of the most popular applications in Singapore because it's a handy bus guide that also does bus arrival times. Unfortunately, it was unusable under iOS4 so anyone who upgraded couldn't use it anymore.
Fortunately, an updated version of SG Buses is now in the App Store that fixes the problem. Oddly enough, it's not appearing in the updates list on my iPhone so you might have to download the app manually.
If you used to rely on SG Buses, this update is a must-have.
