New evidence has emerged that further confirms Apple’s ongoing tests of an LTE-enabled iPhone and iPad. BGR exclusively reported last week that multiple Apple carrier partners are currently testing iPhone models equipped with LTE radios. Our source also supplied a PLIST file containing evidence of the LTE-enabled iPhone. Now, MacRumors has discovered this LTE.plist file in iOS 5 developer builds for both the GSM iPhone 4 and the CDMA iPad 2. While the discovery of these files does not necessarily indicate that Apple plans to release 4G LTE-compatible devices in the near future, it does reaffirm that ongoing tests are being conducted with the new high-speed wireless technology. An additional report emerged last week claiming that several Apple Store locations were having new 4G LTE equipment installed, even providing photographic evidence of the new gear. Once again, this news does not necessarily suggest that 4G LTE-enabled Apple products will launch in the immediate future, but it could be safe to say Apple will be ready to support LTE once U.S. and global coverage is expanded.
