Use of have and what if [closed]

What if I don't have an apple phone but I have apple gloves. Is it correct?

What if I don't have an Apple phone but I have Apple gloves is a perfectly grammatical, normal thing to say.

From your reply in the comment, it wasn't what you wanted to say, which was a simple statement

I don't have an Apple phone but I have Apple gloves.

What if introduces a conditional, but is usually used when somebody has suggested or assumed the converse.

It might be a genuine question in a hypothetical mode:

Next year Apple are releasing such and such on their phones. But what if I don't have an Apple phone?

If it's a real condition, it usually has a slightly sarcastic feel:

A: I need a charger for my Apple phone. Can I use yours?

B: What if I don't have an Apple phone?
