It looks like AP corrected this article on its feed, but the version Mr. Rewrite read with his morning coffee prompted a spit take.
The AP Stylebook calls for BlackBerrys as the plural. It also says no plurals from apostrophe-S except for abbreviations with two or more internal periods (e.g. M.A.'s).
Mr. Rewrite occasionally sees articles with BlackBerries or Blackberries. Avoid these.
