How to Update Google Nexus S I9020 with CM10.1 Android 4.2.2 Stable Jelly Bean

For a phone that originally started off with 2.4 Gingerbread, it’s good to see this one come a long way. One thing that never ceases to amaze us is how the older devices are still made to be compatible with the newer firmware. The reason we love that is because the newer software versions are always much improved, and as such, they need more things. Android does nothing short of a stellar job to keep it under wraps in my opinion. Having said that, we are now living in a time when the latest Apple operating system won’t support the earlier phones, so more than likely that era will be coming over to the little green robot side of things too. It’s easy to forget it’s only been five years since all of this started. They celebrated the 5th birthday recently.

Why is this update so good? For many reasons. Firstly, it has the updated patch that fixes the security issue which was only recently found. The second big reason is that you can’t get Jelly Bean on this mobile any other way because it wasn’t released for it by the Android team. Thanks to the CyanogenMod guys, they have brought it out so everyone owning a Nexus S can now get a hold of 4.2.2 JB. Also worth mentioning is that this is a stable build, which is even more reason to go ahead and jump on this puppy.
