The next version of the iPhone, which may or may not be called the iPhone 5 (most likely not), is expected to be released the third or fourth week of September, following an expected September 12 unveiling.

So, we should have close to a month’s worth of leaks, rumors and speculation to tide us over until then. The latest comes from The Korea Times (via TheNextWeb), which reports that SK Telecom and KT officials say they’ve been in talks with Apple. Kim Yoo-chul reports:

“KT is in negotiation with Apple to persuade the latter to support KT’s 1.8-gigahertz frequency in Korea for the upcoming iPhone,’’ said one KT source, asking not to be identified.

SK Telecom is also pushing for the same. Officials from the nation’s biggest mobile carrier are currently in Apple headquarters in California to persuade Apple to support SK’s LTE frequency for its local customers.

SK reportedly uses an 800-megahertz frequency.

As reported the other day, alleged leaked photos of the device’s motherboard seem to confirm LTE support. As others have noted, this support could put increased strain on the device’s battery.
