I am Nigerian and yes it is possible to buy iPhones in my country, I use one. My apologies for not upvoting your comment, it's customary to do so. Steemit is a social network, not just about upvotes and money but also a community where you get to meet people and build friendship. Having said that, I went through your blog and noticed you post quality things so I followed and will upvote future posts....keep steeming!!!
