Several users have written in to note that T-Mobile suffered a several hour nationwide outage last night, the company's network being inaccessible for many between the hours of 6:00 and 9:30. The company has yet to give an explanation for the outage, but says that the majority of customers should be back to normal. "T-Mobile experienced a network data issue Monday night that affected service for some customers with a 3G or 4G device," T-Mobile said in a statement. "Some customers were not able to initiate a data session, or experienced intermittent data connectivity." T-Mobile is busy installing new equipment at 37,000 cell sites and refarming spectrum in order to launch LTE in 2013.
