You can only buy hardware that runs Apple software from Apple, but Android mobile devices far outsell Apple devices and always have. Apple is and always has been a minority player in the overall smartphone market (and desktop/laptop as well).
Globally, Android has had about 70% to 75% market share, and Apple has always had a much smaller slice of the total. iPhones are not as popular as you seem to think they are. You don't have to believe me, the data proves it:

Sure, but that doesn't change the fact that the iPhone 4 was the single most purchased smartphone model in the US between 2010 and 2011 (during antenna gate that we are talking about).
Android has the majority share because "Android" is anything from a $100 piece of junk to a $1200 phone. If you look at only the premium market, Apple holds ~70% market share.
Despite antenna gate, it still sold plenty, which proves the point about brand trust that the thread was about.
If the brand equity wasn't there, the Galaxy S would have out sold the iPhone 4, but it didn't, it sold half as much.
