On the blackberry, Select the Email Settings Icon and sign in.
Select the ADD button.
do NOT select Gmail. Instead, select OTHER.
in the Email Address.. fill in a bogus email address (like
[email protected])
in the Password field, fill in anything for a password
Click Next.
You'll see a screen that says 'We were unable to configure…" Select I will provide the settings to add this email account, then Next.
Select Personal Email, then Next.
In the 'Email Address:' field, enter your full email address (including '@gmail.com').
In the 'User Name:' Field, enter the portion of your email address before the "@" (i.e. don't include the @gmail.com)
Then enter your password in the 'Password:' field.
In the 'Email server:' field, enter 'imap.gmail.com,' then select Next.
Click Next.
You'll see "processing, please wait…" while it sets things up.
If IMAP access was successfully configured, select OK.
You'll be brought back to the page showing your accounts. Select your Gmail account.
scroll down, Fill in 'your name:' with how you want your name displayed. .
check the box for synchronise deleted items between…
