I'm not trying to argue with you but I believe SSL is enabled for GMail.
After making sure Gmail is set with IMAP enabled in your Gmail settings,
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
In the Password field, fill in anything for a password
You'll see a screen that says 'We were unable to configurexxx8230;"
Select "I will provide the settings" to add this email account, 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.
You'll see "processing, please waitxxx8230;" while it sets things up.
At this point I get an error but it still sets up the account.
When I go back into the account to edit it, it shows the "Advanced Options" that aren't shown in the regular GMail setup account.
In the Advanced Options it shows port 993 and the "Use SSL" box as being checked by default. I'm sure that when you set up the GMail account up automatically using the GMail option that it probably uses the same port and uses SSL. When I setup my @charter.net account this way and then went back and looked at the "Advanced Options" it didn't show the "Use SSL" box checked. I'm guessing that GMail requires the SSL to be checked in order to work.
The down side to actually using GMail after setting it up this alternate way is that your mail will likely be delayed. The regular method of setting up GMail still sets up an IMAP integration with GMail but the mail is instant.
Hope this helps.
