There were other casualties of Apple.
1) Telus in Canada: In order to launch the iPhone 3GS, they had to build out an HSPA network from the ground up and overlay their entire CDMA Network in a hurry. Talk about a massive undertaking. Plus it shows the kind of control that Apple has.
2) Bell Mobility in Canada: Same thing as Telus. Complete overlay of their existing network to cater to Apple and the iPhone 3GS launch.
Verizon waited idly by for Apple to finally launch a CDMA iPhone in January 2011, 1 1/2 years after Bell and Telus bowed down to the fruit.
3) Band 12 LTE: T-Mobile, USCC, and a few other smaller US carriers, making iPhone 6, 6 Plus & iPad Air 2 not fully compatible with the CCA/RRPP program.
Apple is in more control than most people think. Nexus 6 is fully CCA/RRPP compliant, as well as the was going to be Sprint variant of the Moto X 2014 edition.
