The main developer for Empower, Ani, just let me know that they have released an update to their very useful BES Mailbox application. You can pick up version 3 at this link from your BlackBerry or from the BerryReview store.
With this latest release, BES Mailbox now works with OS 4.1, 4.2, & 4.3. I find it to be a very useful application to separate my BES work emails from my private emails.
If you don’t already have it you can pick up a copy for $19.99 from the BerryReview Store.
