Instagram disabled ??? HELP !?

[003]

Ok, so yesterday when i tried to sign in my instagram, it said that it had been disabled for violating the rules. the thing is, i let my friend use my phone so she can go on HER instagram account. apperantly she posted rude stuff on there. but now it wont let me log into my account. i tried logging in on my other friend's phone, and it worked! but somehow it wont work on my phone. So apparently the whole instagram APP has been disabled for my phone! Does anyone know how i can sign in on my phone??? i tried contacting instagram but they never reply. HELP!! does anyone know how i can make instagram work on my phone again?? & plz dont tell me to jailbreak my phone because there isnt a jailbreak for my version. thank u so much!
