Last nudge up maybe ios iphone wallets - seems to coincide with Apple accepting Bitcoin wallets.
They've been accepting Bitcoin wallets and Bitcoin applications for months now. It could be blockchain.info's own wallet, yeah. But not in general, it's already been months since Apple changed its mind.
Blockchain published their wallet on 30th July
Yeah, like I said, their own wallet would make sense. But not wallets in general, since there are others already on the App Store. So that graph is only showing wallets directly on Blockchain.info? If that's the case, it indeed wouldn't show the other wallets at all.
