AITA for refusing to give my 12 years old niece the phone that my deceased son left behind?

I got a call from my sister saying I was the most heartless person in the world.<br><br>My son died when he was 14 in a car accident. It’s been 8 years and I still have everything he left behind untouched and it’s all in his room. My wife asked me multiple times to either get rid of it or donate it, but I refused. She knows better than to argue with me about this.<br><br>My sister visited us last week and she saw his phone on his desk. It was just an old Nokia phone, but it was fully functional. She joked saying it was old school and she used to have one just like it. She even pretended to play with it saying it still had some charge left. <br><br>I didn’t really pay attention to her, but the next day she asked me if I could let my niece (her daughter) use the phone as her birthday present. I was shocked. I told her I wasn’t comfortable with that at all. My niece asked me as well, but I told her the same thing. My sister asked me what was I going to do with it, but I told her it wasn’t any of her concern. I was starting to get annoyed at this point and I told her she had no right to ask for anything that belonged to my son.<br><br>She left, but I got a call from her husband asking me if I could just give it to them for my niece, but I told him I couldn’t do that. I told him to not call me again and ask me for anything that belonged to my son. I told my wife about the whole thing and she didn’t say anything.<br><br>The next day I got a call from my sister asking me why I was being such an asshole. I told her she was the one asking for something that didn’t belong to her and she had no right to do that. She told me she couldn’t believe I was being so selfish, that she couldn’t afford to buy her daughter a phone for her birthday and I was being stubborn over an old phone that had no use. I told her she had no right to call me selfish and to not call me again to ask for my son’s things.<br><br>Now she’s not talking to me and I’m wondering if I might have overreacted just because she asked for my son’s phone. AITA here?<br><br>&#x200B;<br><br>Btw I did buy my niece a present and it was something way more expensive than a phone. I just didn’t tell my sister about it.<br><br>Edit: Yes. My son’s phone is fully functional and it works with my niece’s sim card<br><br>Edit 2: The phone is just a regular one, not a “family heirloom” or anything like that. It’s just a phone that my son used and I kept it as a memory of him.<br>Some people are making it seem like I’m being irrational and even psychotic because I didn’t toss it in the trash or get rid of it. I just kept it because it was his and a memory from him to me.<br><br>Edit 3: When I said I kept everything “untouched and it’s all in his room” I meant his clothes and personal things. Not his toilet or dirty stuff.<br><br>Edit 4: Some people are saying I should get the phone checked by the authorities and that there must be some dark things in it that I’m trying to hide. I think these people are just being delusional and seeing things that aren’t there. My son wasn’t a bad kid and he didn’t do anything wrong. <br><br>Edit 5: I understand my answer might not make perfect sense to some people, but that’s okay. I’m not going to get rid of the phone or throw it in the trash just to please strangers that I don’t even know.<br><br>Edit 6: I wasn’t expecting this post to blow up. Thanks for all the awards<br><br>Edit 7: Yes. The phone is just a regular phone. Not a collectible or anything like that. Just a phone like most of us have used. The point isn’t the phone itself, but the fact it was my son’s phone.
