HTC DROID Incredible - Manual (Page 112)

11 Accounts and sync
Tap Add account, and then tap the account type you want to
add.
Follow the onscreen instructions to enter the account
information.
When you have finished, the account is added to the list on the
Accounts & sync screen. Depending on how you configured the
account, the new information may start synchronizing with your
phone.
Synchronizing with a Google Account
Signing in to your Google Account lets you synchronize Gmail/Google
Mail and your Google contacts and calendars between your phone
and the web. You also need to sign in to a Google Account to use
Google applications such as Google Talk™ and Android Market.
You can add more than one Google Account on your phone. However,
subsequent Google Accounts can only synchronize Gmail/Google Mail
and contacts. Other Google services use the first Google Account you
added.
Press HOME > MENU, and then tap Settings > Accounts &
sync.
Tap
Add account > Google.
Follow the onscreen instructions to sign in to an account or
create a new account.
