KT, a company partnered with Apple to sell iPhones in South Korea, revealed its plans to begin selling the 4G iPhone as early as April. We can obviously expect the phone to include new radio hardware for connecting to 4G networks, and KT’s reports indicate the phone will feature a new dual-core CPU for a speed boost. The screen is to be switched from a standard LCD to an OLED model, which could mean a brighter picture and reduced power consumption. There could also be a front-mounted camera for video chat and a battery that’s finally removable by the end-user.
