The next generation Apple iPhone – potentially called the '4G', although it's unlikely to use fourth-generation wireless technology – is going to be announced in April, according to a couple of press reports from South Korea.
It's suggested that the new device will use a faster dual-core processor and an OLED display. Other potential improvements include video calls via a front-facing video camera, improved graphics – and maybe even a removable battery. [Sources: KoreaTimes.co.kr; TelecomsKorea.com]
