You can use the universal box to access Gmail and all your folders in Gmail. This will allow your universal box to have text, Gmail and an exchange email account - basically what many blackberry users have grown accustomed to with the one mailbox. Just be sure to disable notifications from the native Gmail application on the phone so you won't be notified twice. Here are the instructions to configure your Gmail account through the add email account.
To configure the 'Email' app on an Android device for access to Gmail, just follow the steps below:
Enable IMAP in your Gmail settings.
On your phone, press < Home >, then open the Email application.
On the 'Your accounts' page, select Next to get started with setup.
Enter your full Gmail address and password, then select Next.
On the next screen, you can give the account a nickname and choose the name to display on your outgoing messages. Tap Done.
And you're done. You can verify your settings from the Inbox view by tapping < Menu > > Account settings.
Incoming settings
IMAP server: imap.gmail.com
Port: 993
Security type: SSL (always)
Outgoing settings

Now that your account is set up, learn how actions in your client sync with Gmail.
