Forbes is reporting that U.K. carrier O2 will abandon its i-mode service after only being able to sign up 260,000 users to the Internet phone service in the past two years. Additionally, the mobile carrier will not sell any new i-mode-enabled handsets from the end of July, but despite this would continue to support those quarter of million users for the next two years. This technology, adds Forbes, has been wildly popular in Japan but has failed to attract the same level of interest in Europe.
