Hi all well my 6 regular only shows 12gig used
What ha think ... Could I get a 6plus 16gig?
Does that mean I would have 4gig free or less because of the iOS ?
Not quite. The 16GB only has about 10GB free right off the bat. So, you would be shy 2GB with what you have on your current phone. I'd get the 64GB if i were you. With apps getting larger and larger, it would be future proof as well.
