Unlocked iPhone 5 owners on T-Mobile's network might be able to update their devices to LTE a bit earlier than expected. According to TmoNews, the carrier is said to be sending out an update on April 5 that will enable LTE, Visual Voicemail, and more.
"The T-Mobile Carrier Update is a minor iOS software update that enables official iPhone support by T-Mobile," a notice sent to TmoNews says. "When installed, the software update enables a handful of capabilities like Visual Voicemail, MMS Settings, and Network/Device optimizations that customers do not have access to today. On April 5, the software update will begin being pushed via OTA to all iPhone devices on the T-Mobile network with iOS 6.1.x or higher."
T-Mobile is on April 12, but many customers already use unlocked AT&T or other iPhone devices with the carrier. Theoretically these customers wouldn't have been able to update to 4G until the April 12 launch date.
Starting April 12, T-Mobile's iPhone 5 can be bought for a $99.99 down payment with unlimited text, talk, and data and without a two-year contract. Customers who want to finance the phone will pay $20 a month for 24 months. Also, the new iPhone 5 has been specially tuned to , which at a fast 20Mbps or more.
