Hey guys One of my friends updated her iPhone software to 4.1, and lost her unlock. I no longer have a 3Gs to check which version of the baseband firmware she has. Does anyone know which version comes with 4.1? Anyways, she asked me to unlock it for her and I was wondering if jailbreaking it for her would get rid of the insert a valid SIM message? If not how would I go about jailbreaking her device?
