Instafire is a nice product to get fire started!
Nah i actually googled it up and i think that wouldn't work either. If it does have to function to create accounts it will probably stop at 10 accounts saying you created to much accounts on that device.
Though i did read somewhere that you can take a iphone and actually hard-reset the device after creating 10 accounts so you can create another 10 and so on..
Yet this will be time-cosuming.
I am still looking for a way to create instagram accounts.
Well, creating the accounts wouldn't be the biggest problem. Getting them phone verified is my issue.
