I need help understanding the phrase "I've got something" in English.
I know that it is an informal way to say "I have something" and that it is used as Present Simple rather than Present Perfect. But my question is, can this expression (I've got...) be used as real Present Perfect? I know that in American English, it can be used this way, but the form "got" is changed into "gotten" (like, "I've gotten a phone recently").
And what about British English? Can I use "I've got" in Present Perfect there? Like this:
I've got your email. = I've received your email.
