Korean Carriers Negotiating With Apple For 800/1800MHz LTE Service In New iPhone
One of the expected features of the upcoming iPhone 5 is LTE support and it is expected to support LTE in some markets (much like the iPad 3, but hopefully with further roll out). Because different countries use different frequencies for LTE, it's quite difficult to make a phone that supports them all.
The Korea Times has reported that sources at the Korean carriers that carry the iPhone, SK Telecom and KT are claiming to be in negotiations with Apple about LTE service in their next iPhone.
Some feel that this discussion is quite pointless, given that the iPhone 5 is expected to launch in just over a month, so the hardware capabilities of the device have been finalized already. Maybe the iPhone does include support for the Korean LTE bands, 800MHz and 1800MHz, and the negotiations aren't over inclusion, but merely pricing or other contractual terms.
The third generation iPad does support LTE, but only on the 700MHz and 2100MHZ frequency bands, meaning that very few carriers support it - in the U.S. AT&T and Verizon use the frequency and Bell, Rogers and Telus in Canada can also support LTE. Carriers in other countries use different frequencies, so they can't use LTE - Apple even got in trouble in Australia for claiming the iPad 3 had 4G support, but no Australian networks supported it.
