Iphone 4 Restore Data with no Back up
I just got an Iphone, that my mother used to use, I have never used an iphone before. I'm traveling at the moment, so my boyfriend gave his laptop to use for this period of time. I tried to download something but was required to create a new ID Apple account, which I did, then it said that I had to update my IOS, in order to do that I had to connect the iphone to the laptop, as soon as it updated itself, I realized that I'm holding a phone with my boyfriend's data in it because it was his itunes on a computer. I'm feeling desperate because as i said I'm traveling and I took bunch of pictures already that just have disappeared.. Is there anyway I can restore them, because I had no backup? not even ICloud... only Apple account. I would really appreciate any suggestions!
