It seems that multiple US carriers are testing LTE Enabled iPhones which run a special version of iOS which carries special files need for the phone to work with the LTE network. The information was found deep down in the new firmware.
The iPhone 5 will almost certainly support the marketed “4G” called HSPA+ on GSM networks but so far only Verizon has launched “true 4G” in the US with the new LTE technology. It was previously reported that the LTE enabled chipset Apple’s waiting for will come out in 2012 since the current ones compromise battery life, size and design issues.
While we can’t confirm that the upcoming fifth-generation iPhone will be able to support 4G LTE, we can now exclusively confirm that Apple’s carrier partners are testing iPhone models with LTE capability. BGR has obtained evidence of an internal iOS test build from one of Apple’s major carrier partners, and buried in the firmware is a property list (.plist file) for LTE.
As long as the battery doesn’t die every few hours we’re happy.
