I just got this 4s. I tried a few different sim cards and it accepted it. How can know what software was used to jailbreak it? When I click cydia, It does not show the regular cydia options such as packages or sources. It shows 20% of 64GB capacity. I am thinking that something has gone wrong during jailbreak. Is it ok to jailbreak it again using evasi0n? Please advise. Thanks. EDIT: How can I know if it's a permanent unlock or software unlocked? Do I need to preserve the modem firmware 1.0.13?
