Are there unique user agents for mobiles like there is with pcs or do all models of iphone for isntance look the same to a site like instagram? Need to know if I can skip the step of having to make a unique phone for each account and just clear cookies on the same phone for footprint purposes. Asking a bit some ppl have said emei numbers. So I guess me real question is how do you do the equivalent of randomizing user agent like you do on pcs but for phone emulation? -i read there is something for bluestacks but I'm using android-sdk.
