Iphone4 SMS ringtone is very strange

First of all, from my personal point of view, this problem is completely different from jailbreaking by swiping a computer. It's the phone itself. Of course, it is also possible that there will be problems when you come out. I think the answer on123rd floor is ridiculous, as if I understand it very well. . . For example: buy a TV, the sound quality is not good, the merchant asks you to brush it or other methods, are you willing? The landlord still doesn't take your mobile phone, it's hard to say, the responsibility lies with you, insist on changing it! Safeguard consumer rights!
