Can I return my defective iPhone now?

My carrier is T-Mobile. It's been a month since I received it and activated it. Is it too late to return it? I've been on vacation for a while and I just realized that it's defective. Please answer quick! I'm so worried they won't accept it or they will make me pay for another one. Keep in mind, I have warranty

Most iPhones have a 1 year warranty on the phone itself. If the phone is what is defective, send it to apple for a new one. If the problem lies with the carrier, call them and try to resolve it.

  • When you give APPLE a defective IPHON do they give you a reconditioned one back? My IPHONE had a defect, still under warranty, so I took it to an Apple MAC store and after a few days they gave it back, supposedly repaired. Now the replaced IPHONE has a problem, different than the previous problem I'm now having a problem with the taking a photo. Do they just replace your phone with a reconditioned one they say no but?

Siri and the little slot on the right side are not "included".Is my iphone a defective? Please, if anyone, answer my question.thank-you
