Twitter users are welcome to stay connected through T-Mobile service. Rumors that T-Mobile blocks the service are false. T-Mobile confirmed with Twitter that there was a technical issue between the two companies’ systems that temporarily prevented some customers from utilizing the service this past weekend. That issue has since been resolved and the companies are working to prevent such incidents from re-occurring.
