Malte Ubl T-Mobile and AT&T were supposed to merge in the anti-consumer ecstasy to make largest US-wide GSM carrier. Alas the deal was not allowed by the regulators, and in initial offer AT&T had "break-up" clause that gave T-Mobile some spectrum, cash and roaming agreement (was supposed to be used to prop up regulators to approve the deal "otherwise we lose soooo much" type of thing I guess)
