By Will Knight Many thousands of Japanese mobile internet phones have been recalled after manufacturers discovered a glitch that can prevent the devices receiving calls and data. The flaw affects some Panasonic Digital Mova P503i HYPER phones, which are manufactured by electronics company Matsushita. Japanese wireless network operator NTT DoCoMo said that in certain areas the phones have been found to malfunction, being unable to access data or voice. The company believes that the timing of transmissions between base stations and phones underlies the problem. The flaw has been found to affect 100,000 out of 800,000 phones of this type. NTT DoCoMo has decided to stop selling these phones until 23 July. NTT DoCoMo said that users hit by the glitch can visit a shop from 24 July so that a software patch can be applied to fix the error. The company also plans modify base stations to control the timing of transmissions to prevent the problem happening again. This work should be completed by 20 August. The phones use NTT DoCoMo’s iMode technology for accessing the internet through mobile phones. The roll-out of more powerful mobile phones will go hand in hand with the forthcoming introduction of the world’s first “third generation” (3G) mobile network in Japan. Launch of the new network has been delayed from May to October to give network operators more time to carry out testing. When it is fully functional it should provide up to two megabits per second data transfer. The network has been designed to be compatible with future European and US mobile networks. Paolo Pescatore, a mobile phone analyst at research company IDC in the UK, says that these problems are likely to multiply with the introduction of the new 3G network. “Whenever you have a new network there are problems” he says. “Being able to integrate it with the old network may be a problem. Then of course there are the handsets.” This is just the latest telecommunications glitch to hit Japan. In May, DoCoMo recalled thousands of phones built by Sony because of a software glitch. Competing telecommunications carrier KDDI recalled Sony handsets in July because of faulty batteries. The Digital Mova P503i HYPER is one of the latest phones to be offered on DoCoMo’s existing network with increased functionality. The phones use the platform independent programming language Java to perform complicated tasks. They can download and execute new applications,
