As iOS 5, the most advanced mobile operating system is released, users are looking to upgrade their device’ firmware to iOS 5. Users who keep official firmware and don’t like to jailbreak their devices can upgrade without any hesitation but what about folks who don’t even like to use their device without all those tweaks? Well here are some things to keep in mind before you go for the update:
There is no untethered jailbreak released for iOS 5 yet. Though tethered iOS 5 jailbreak for all iOS devices except the iPad 2 is available but Cydia/MobileSubstrate and the tweaks that use MobileSubstrate still have some moderate bugs. In case you don’t know, tethered jailrbeak is a kind of jailrbeak in which you have to tether your device with your computer everytime you reboot your device. In simple words, if you reboot your device, it won’t boot until you connect it with a computer having necessary jailbreaking tools. On the other hand, untethered jailbreak is inverse of tethered jailbreak, means you have your device jailbroken for life. So untethered jailbreak is recommended.
iOS 5 comes with new baseband, means that iPad 2 GSM/CDMA users if once perform any kind of restore, and if apple is no longer signing that firmware, they will get stuck in recovery with no way of getting out. This is because there is no public bootrom exploit for iPad 2. So be cautious about it or you will lose your device.
If your iPhone rely on unlock, don’t update iOS 5 with stock firmware via iTunes as it will upgrade the baseband of your device. Instead cook a custom firmware using Redsn0w or Snowbreeze as they will preserve the baseband and then restore to iOS 5. Once you do this, you can unlock iOS 5 using ultrasn0w 1.2.4
iPhone-dev team and other jailbreaking communities are currently working to bring untethered jailbreak for iOS 5. So be patient, don’t mess up with your device and stay happy 🙂 If you need any type of assistance, drop your comment in the comments section below.
