If you’re a T-Mobile subscriber who’s been accessing the carrier’s HSPA+ network with an unlocked iPhone 5, don’t worry about having to buy a whole new device to use its recently launched LTE network. TmoNews reports that T-Mobile will push out an update to its unlocked iPhone 5 subscribers on April 5th that will give the device access to the AWS spectrum bands used for T-Mobile’s LTE services. Of course, since T-Mobile’s LTE network is only live in seven markets right now, you’ll probably still be relying on HSPA+ connectivity even after installing the update this week. TmoNews also says that the update will also give unlocked iPhone 5 users access to Visual Voicemail “among other features.”
