Softbank Mobile Corp. unveiled new cell phones Tuesday boasting applications for the micro-blogging service Twitter.
Softbank CEO Masayoshi Son, an avid user of Twitter, said the move is aimed at making it easier for more people to "tweet," or comment, via their cell phones.
The number of Twitter users in Japan has been growing rapidly, but not many people were using the medium through cell phones except for iPhone users, which Softbank offers, he said.
