It hit a few snags along the way, but T-Mobile's merger with MetroPCS now appears to be all but a done deal. Bloomberg is reporting that MetroPCS shareholders voted to approve the deal this morning, following a recommendation from two previously opposed shareholder advisory firms that the merger be approved last week -- and approval from the board before that. According to Bloomberg, the final terms of the deal give T-Mobile parent Deutsche Telekom a 74 percent stake in the new company, with MetroPCS shareholders receiving a $1.5 billion cash payment. Most notably for T-Mobile, the deal brings nine million new prepaid customers into the fold, as well as the all-important wireless spectrum that MetroPCS currently owns.
