From the website you have several options available under 3 different tabs. Under "My Device" you can view the current location of your device, make your BlackBerry ring or display a message even when on silent or locked, as well as lock or wipe your device --all very handy options to have if your BlackBerry is lost or stolen. This page also shows what BlackBerry you have, your PIN and phone number, as well as battery and signal strength! The "My Data" tab shows an archive of your back-ups and details about each. Under "Manage Devices" you can see all the devices you have on your BlackBerry Protect account and their details, as well as give them a custom name, handy if you have multiples of the same model.
All in all, it's a good redesign. Check it out when you get a chance, though hopefully you'll never have to use it in the case of your BlackBerry going missing.
