i can't login on instagram via my phone. i tried uninstalling, reseting phone to factory settings. none of it worked. after a 2 day research on the web, figured i have to change my udid. could be easy if i had an iphone, but i have an htc android phone. would really appreciate it if someone could tell me how to do this. i read on some sites about it, but they just give some codes. they don't tell what to do with them, like where i'm suppose to put the code or if i have to edit/re-write anything. i'm so lost. please help!
