Working with two devices can be a pain, but the new Bridge app released today will allow you to access their contacts, calendar, email and BlackBerry messages on their phone or tablet via the Bridge app without a tethering feature, and it will even allow for the opening of attachments for emails.
What won’t be a part of the app for free, however, will be the browsing of the Internet or an intranet. Functions such as those will still require you to have a tethering plan.
Basically this comes down to being an easy way to mirror your information between the two devices and allowing you to consume it in a way of your choosing. And, hey, it’s free, so no harm in giving it a try.
