contacts storage on android 2.3.5 Is there a way to have access to the file/s that list the contact details on an Android 2.3.5 phone? My contacts storage is growing up to many MBs, and I would like to be able to delete some of these contacts from the stored files with a scripted solution.
I'd recommend you to use GUI of Contacts app for clearing contacts, but if you are really interested in it, this is the database used to store contact details: /data/data/com.android.providers.contacts/databases/contacts2.db. To alter anything inside it, you need root access and proper SQL queries.

The location of database may vary depending on device..
