NTT DoCoMo may have given clues to Apple making LTE a staple of its next iPad an iPhone. A claim in Japan's Nikkei asserts that the carrier is hoping to carry a 4G iPad by the summer and a matching iPhone by the fall. Apple chief Tim Cook had supposedly had NTT DoCoMo VPs Kiyoyuki Tsujimura and Takashi Yamada visit Apple's campus to successfully make a "basic agreement" and had been hashing out details such as minimum shipment volumes.
