What’s a semi-tethered jailbreak? We all know that a tethered jailbreak needs access to a computer in order to reapply after a reboot and that the untethered one is persistent. A semi-tethered jailbreak is a new concept which somehow sits in between the two above.
Say you’re out and about but your beloved iOS 5 device is power cycling (for whatever reason). If you were running a tethered jailbreak you’d be wishing your computer was close in order to get you passed that Apple logo. With the semi-tethered jailbreak you phone will start normally and it will be able to do basic tasks like making a phone call, sending a text, using built-in applications and so on. On the down side you’re not going to be able to use Safari to surf the internet or use the mail application. Sounds like an excellent choice until that untethered solutions is available. Adding to the negatives: the phone will take longer to boot.
