How to delete all contacts from an Android phone?

When we started developing a cross-platform 'Contacts Sync' app, we found that in Android there is no way to do it straight. I was quite skeptical that a feature like that was not available :-)

Anyway, we wrote an app, intuitively called "Delete All Contacts" :P and started using it. The code is pretty trivial (if you can see a couple of posts earlier "Contacts in Android")

However, we added some jazz (like our logo) and a feature to delete contacts with a particular name / pattern. (My Beceem friends would fondly remember the set of commands I created in a debug tool called swin that let us read / write variables with a particular pattern in the name)

To download this app, just right-click here and save the android package. Then use 'Apps Installer' or adb to install the program.
