The iPhone 4S’ launch in Japan was marred by an unfortunate SoftBank server issue. The Wall Street Journal reports that a server glitch led the company to suspend sales nationwide for three full hours—the first three hours of the launch. “I am sorry for the inconvenience. The registration system has been restored,” SoftBank Chief Executive Masayoshi Son announced over Twitter at roughly 11:15 am Local Time. The launch also marks the end of iPhone exclusivity for SoftBank, as rival carrier KDDI is also offering the handset, beginning today.
