Apple testing 4G LTE iPhone?

A new rumor for 4G LTE iPhone, we've learned, That's a new report from BGR which has recently been published online for the world to know, that it seems Apple is already testing an iPhone with LTE capabilities.

According to BGR,

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. This doesn’t necessarily mean every Apple device that’s about to be released will feature an embedded 4G LTE modem, but it certainly means Apple isn’t sitting on the sidelines as 4G LTE networks continue to roll out around the world. Plus, when Apple finally does make a 4G LTE device, the battery might actually last longer than a few hours.
