I just got off the phone because of issues getting gmail to work with the new updated BIS 2.0. I have read of the workarounds on this forum, but hadn't seen the "OFFICIAL" way to do it until I received this document from a Cingular employee.

*Important note, if you have over 400 GMAIL emails you should read this too.

Apologies if this exact guide/information has already been posted.

The following is a Cingular ATG(R) eServer solution:

UPDATE January 16, 2006:

By default, Gmail allows the BlackBerry Internet Service access to the first 400 items on the Gmail POP mail server. As soon as the number of items on the POP mail server exceeds 400, the BlackBerry Internet Service will no longer be able to access new messages. To resolve this issue, clear and reset the Gmail Forwarding and POP settings.



Change The Gmail account may also be configured with BlackBerry Internet Service 2.0 from a RIM BlackBerry device.

Fix
Prerequisite:

New Users: Creating a new BlackBerry Internet Service account.
Existing Users: Logging into the BlackBerry Internet Service.
A valid username and password for the Gmail account.
Enable the Gmail account for POP3 access.
Up to 10 e-mail accounts can be integrated through the BlackBerry Internet Service.

Integrating a Gmail account:

Access the BlackBerry Internet Service

In the "Existing E-mail Account" section, click Setup Account.


Enter the appropriate e-mail settings and click Next.


E-mail Address:
Password: user defined
Confirm Password: user defined

A confirmation will appear when the account has been successfully integrated. Click OK.


The integrated account will appear in the "Valid E-mail Account" section.

New e-mail will be sent to the RIM BlackBerry device.



Suggest a FixAn individual service book will be received for each integrated e-mail account. Each integrated e-mail account will have a separate Messages inbox icon on the RIM BlackBerry device.

actually this is true w/ 1.8
and it's not just w/ BIS...it's actually Gmail who stops the email from popping once you have 400 emails on their POP server

who knows if they'll change this when they're finally out of beta - or if this is going to be their standard

as well - if you've got your Gmail set up in your Outlook you won't be able to receive it on your BlackBerry - Gmail only allows each email to pop once (and in one place) So you'd have to set up a forwarding rule to recieve on your BlackBerry

again - who knows if this will change when Gmail is out of beta testing

Using the documented forwarding rule (as documented on this forum) seems to be more consistent and causes less problems (IMO). The downside to the forwarding rule is no email reconciliation.
