Bitfone Corp. of the United States is negotiating with several major Japanese phone makers to sell them its wireless software-repair program, Bitfone Chairman Gene Wang said in a recent interview with Kyodo News.

Wang said the company's mProve Agent software would free mobile phone makers from the need to recall mobile handsets and spare users from having to visit service centers.

He said the system would enable mobile phone makers to slash expenses involved in recalling and repairing handsets when the software powering them is found to be defective.
