Racism makes conformity the highest priority rather than result oriented professionalism. They were sold off by Infineon to Intel, Intel then sold them off to apple.

As of yet it has been 3 years and they couldn't come up with a viable modem for apple. Apple is still using Q modem. With the way things are going apple will still be sourcing the q modem for years to come.
