Carriers in Korea are currently voicing concerns to Apple over compatibility issues with their networks, the Korea Times is reporting. The LTE frequencies used in the nation are slightly different from those used in the U.S.

Along with this report, the fact that the new iPad runs on LTE networks also points to the new smartphone having the same ability. The iPhone is also rumored to include a more powerful battery that can accommodate LTE connectivity without draining too much power.

The iPhone 5 will be released internationally on Oct. 5, just a few weeks after it is launched in the U.S.

iMore's Rene Ritchie, someone with a track record of being correct with Apple predictions, stated that Apple will begin offering pre-orders for the next-generation iPhone on Sept. 12, the same day the device is expected to be announced.

She also added that it will be released by Apple on Sept. 21 alongside a new 7.85-inch iPad Mini. This new tablet will be launched by the company to compete directly with Google's Nexus 7 and the successor to the Amazon Kindle Fire.

The iMore report also pointed out that the international launch of the iPhone will take place in early October, with Oct. 5 being the most likely day. This fits in with Apple's normal strategy as the company has been known to delay international launches to ramp up sales.

The company did this with the iPhone 4S releasing it two weeks after its U.S. launch.

The iPhone 5 is rumored to have a 4-inch display with 640 x 1136 pixel resolution and a redesigned nano-SIM card slot. It will also feature LTE connectivity and a larger battery to accommodate the network.

Along with those features, it will also most likely come equipped with an NFC (near-field -communications) chip, and a redesigned 9-pin smaller dock connector.
