With the news of the T-Mobile USA and MetroPCS merger just settling, company shareholders have filed a lawsuit trying to block the deal.

According to the TMONews, MetroPCS shareholders are calling the deal "drastically undervalued" and claiming that MetroPCS' board is "conflicted and serving its own financial interests." The lawsuit was filed in Dallas, Texas against MetroPCS, T-Mobile USA, its German parent company Deutsche Telekom, and MetroPCS' CEO and board of directors.
