(Telecompaper) French operator Iliad is talking to private-equity firms about teaming up to make an improved offer for T-Mobile US, people familiar with the matter told Bloomberg. Iliad's discussions with potential partners may accelerate after Deutsche Telekom indicated it's willing to negotiate with a price of at least USD 35 a share. The German company hasn't received a new proposal and there's no guarantee a higher offer will be made, the report noted. In addition to US buyout firms, Iliad has been talking to companies and sovereign-wealth funds about supporting its offer for T-Mobile. Iliad's previous offer of USD 33 per share in cash for a 56.6 percent stake in T-Mobile was rejected as too low a month ago.
