In English, it's correct grammar to include an article ("the" or "a") before a singular common noun. "iPhone" is a singular common noun, because it's not a discrete entity like Jupiter or Bill Gates, it's a consumer product - there are many, many iPhones. It's also -- despite Apple's marketing to the contrary -- not a singular or distinct concept, at least not in the context of your post. If you prefer to drop the article because it conveys your idea better, you can pluralize the noun. "iPhones" is a completely valid drop-in replacement.

No spite/sarcasm intended - I am genuinely trying to be helpful.
