For US users this may not be much of a big deal – WhatsApp says the big three OS’s account for 99.5 percent of sales today – some regions of the world where BlackBerry devices or older OS’s are still fairly popular will suffer more.
Still, you can’t really blame WhatsApp, as it’s supported more platforms than the vast majority of competitors for some time no. It’s somewhat surprising they held out on older phones for so long; I mean, who still updates on Symbian?
If you are on one of the soon-to-be-unsupported operating systems, WhatsApp is offering obvious advice not everyone will be happy to hear: upgrade to a newer phone.
