I work for a company that wants all phones to be owned by them, so those who do not expense it own Android, maybe 10% of the company, then there are the Company allowed devices (Blackberry, iPhones) we are slowly moving to iPhone although we use Bes10 services for exchange, so BB Phones account for 20% but the rest 70% is iPhone and since the company allows either an iPhone 5S 32GB, 6 in 16, or 64GB, or 6+ in 16 or 64GB, most people are going to the 6 and 6+ now.
Only the Rebels who want to use android and Touchdown for email can access the company network, though if a company offers you a new phone every 2 years and pays the bills for it, iPhone is gaining popularity here. I would say 1-2 years ago it was 40 Android, 30 iPhone and 30 BB
