For you all Bold users running OS 7.0, OS 7.1 is ready for release. Blackberry will be pushing the official OS out over all carriers through out the week. Here are a couple of the new features.
Mobile Hotspot:Turn your BlackBerry 7.1 OS device into a Wi-Fi® router anywhere, anytime! The new OS seamlessly provides Internet access for up to five Wi-Fi devices, including laptops and tablets. Wi-Fi® Calling (where available):With BlackBerry 7.1 OS, you’ll be able to make Wi-Fi calls using your carrier’s Wi-Fi calling service (aka UMA-lite or GAN-lite). Wi-Fi calling allows you to save your talk time minutes and make phone calls over any Wi-Fi network. Not all carriers offer such a service so check with your carrier for availability.
