With the deal off the table, T-Mobile still could be a suitor for a carrier with a much smaller footprint than AT&T. AT&T has put T-Mobile in play and you can bet that there are some M&A bankers who have been playing dialing for dollars with some of the smaller regional carriers to gauge interest in a T-Mobile acquisition. Of course, most of the regional carriers don't have $39 billion to spend, but if you take a company with deep pockets dying to get into the mobile carrier business, another bid could be possible. Dish Networks recently said that if the deal with AT&T fell through, it would be interested in partnering with T-Mobile. While being a partner isn't the same as owning another company lock, stock and barrel, it is hard to believe that some large tech related company somewhere would not be interested. Even a company in the entertainment business like Disney might be open to a deal. And what about Apple or Google? Both have a ton of money and might be open to some vertical integration.
