Was ist der Unterschied zwischen I got an iPhone und I have an iPhone ?Du kannst auch einfach Beispielsätze geben.

“I got an iPhone” - One would use this phrase to answer someone asking them about a recent purchase. One would usually answer with “got” when someone asks them a question with the word “get”

For example:
Friend 1: So what kind of phone did you get?
Friend 2: I got an iPhone

Or another example with “get” and “got”:
Friend 1: Did you get the message I sent you?
Friend 2: Yeah, I got it


“I have an iPhone” - One would use this phrase to answer someone asking them about a phone (or any other subject) that they have had in their possession for a while. One would usually answer with “have” when someone asks them a question with the word “have”

For example:
Friend 1: What kind of phone do you have?
Friend 2: I have an iPhone

Or another example:
Friend 1: Do you have the notes from class?
Friend 2: Yes, I have the notes

NOTE: Saying “Yes, I got the notes” instead of “Yes, I have the notes” here would not be proper sentence structure.

In terms of which is more casual, both are commonly used so it is okay to use either as long as you follow the proper sentence structure.

I hope this explanation was clear :)!
