Motorola in an SEC filing on Friday confirmed a heavy dependency on Verizon for its success. About 28 percent of all of Motorola's net revenue in 2010, including only the mobile group that split off this year, could be attributed solely to supplying Verizon with phones. The figure could almost exclusively be attributed to Android phones and was portrayed as leaving the company vulnerable if it lost some or all of Verizon's deal.
