I wanted to get my unlocked IPhone upgraded, So I went to this shop That fixes broken iphones. He upgraded it, but then he couldn't unlock it back. So he gave me a substitute phone and told me that he'll factory unlock it for me for $60 and he'll call me once he's done He said it'll take a least one day (and he said that apple is down for maintenance or something). He didn't gave me no receipt or proof that he is working on my phone.
Do you think he stole my phone?
I didn't pay him yet.
His shop seems legit.
I'm just kinda worried.
Added (1). I'm talking about unlocking it as you can use different phone providers like T-Mobile or At &t. When had my phone I had to use a gevey sim, now he said that the given sim wouldn't work and he has to factory unlock it so it wouldn't need the Garvey sim anymore.
