That may be the biggest problem BB has, dropping support for various apps or simply not offering newer ones. Simple upgrades can cause Apps a user wants to be obsoleted and some feel necessary to switch devices. BB may think it will force users to upgrade to their newer deices but sales show that is not happening. Apple tried the same tactic and now are seeing a big slowdown in sales. Users want a stable supported device and one that will be able to use new apps as they appear. They also want to know they are secure and don't have to worry about hacking like the Android world is now experiencing.
