I (16F) have recently gotten my phone stolen and broken (I have made a post regarding it that you may read if you are looking for the whole story). This phone was special as it was a gift from my mother for working hard in school, as I had gotten through a lot and so got a slightly better phone than my sister (she has an iPhone 11 64 GB and I have an iPhone 11 128 GB). I have been gifted an iPhone 13 by my father (from a trustworthy reseller for cheaper). I am quite clumsy, which I hate, so I instantly decided to buy protection for my phone (screen protector, camera, phone case, etc., and even a PopSocket) with my pocket. Later, I realized my younger brother, whom we will call A (13M), was still stuck on his hand-me-down phone, which had been glitching a lot recently. As much as I disagree with children/young teens having phones, he is reaching the age where it will become fundamental in his life not to forget that throughout the year, we (my brother and I) travel to different countries 4x a year thanks to my mother’s company with other kids our age. With these details, I decided that I would fix my old phone and would give it to him as a present (another + since I couldn't get him a gift for his birthday) and started selling on Vinted for some time until I had saved enough money (saved 150€, paid 120€) to get it completely fixed, almost brand new again, and also bought accessories for him (phone case, screen protector, and new charger), also due to money being tight at the moment, and I didn't want to make my mom feel bad.

After a while, I finally gifted my brother his new phone, completely repaired. He was very grateful, and my mother was proud of me, but the problem arose after my older sister, whom we'll call T (18F), started getting mad at me for wasting money again on a new phone, as I can't "take care of one," and so I shouldn't be getting a better one than her. Although I can admit I'm not the best, I am trying to improve my clumsiness because it's not cute or funny, just annoying, especially seeing as my phone hasn't got a scratch on their phone while having no protection on it whatsoever, whereas I have run through phones due to it and made my mom waste money. So I felt very discouraged and upset. My mom defended me and grounded my sister, but I still feel as though I don't deserve the phone.

Should I give my phone to my sister and take her phone? AITA?
