Hello, I purchased an iPhone 5 from Cricket Wireless about a year ago and it is about time for me to change my provider. I have contacted Cricket and they refuse to unlock my phone for use with other US carriers they will only unlock it internationally. I find this extremely frustrating because I have paid over $700 for this phone and it will eventually become a $700 paperweight if Cricket will not let me change my carrier. Does anyone know if it is possible to unlock my phone myself, legal or not, does not matter to me. Thank you.
