Over the last couple of hours we've seen a steadily increasing flow of tips from users reporting their T-Mobile data service is completely out on 2G, 3G and 4G,, and now the company has confirmed the problem. According to the tweet from its official account the "network data issue" is only affecting service for some of its customers, which jibes with the reports we've received of some users still connecting without a problem. There's no ETA for a resolution, but we'll let you know when we hear more about what's going on. [Thanks to everyone who sent this in]
