This application does nothing on its own; it is useful together with applications managing contacts. MyAccounts will install a new contact-account-type called MyContacts. Once the application is installed, you can go into Settings -> Accounts and Sync -> New Account. By selecting MyContacts you will create a new account which will be visible to all contact related applications and whose name is MyContacts. Typical use of MyAccounts is with applications like MyPhoneExplorer or ContactLoader (soon to be released). These applications will be able to use the account created by MyAccounts. MyAccounts does not come with any synchronization mechanism. It really only declares a contact account. That’s all. If you need to add or edit contacts from the MyContacts account directly on your phone, you will most certainly not be able to do so using your default contact editor. For this purpose, please install the application called "Contact Editor Free" or "Contact Editor Pro".
