I have been part of the Android scene for a little over a year now but have fallen for the OS with a plume. I purchased my entry Android device in December 2010 a Samsung Galaxy Tab 7” and soon followed up this up Nexus S smartphone and not much after that with an ASUS Transformer 10.1”tablet.
All of these devices at one time have run the latest and greatest versions of Android, but since Android is a fast evolving animal it always seems you are out of date.
I have been running Froyo , Ginger Bread and Honeycomb but come December 2011 Google’s Android again evolved and Ice Cream Sandwich was born a unification of Honeycomb and Ginger Bread that brought together both the phone and tablet OS in to a one size fits all release.
The first device to use this latest incarnation is of course the Nexus Galaxy a naked Android phone made by Samsung but directed by Google the creators of the beast that is Android an introduction to the newest member of the OS family a Google’s platform preview vehicle if you will.
But and yes but being a truly naked install there is a another phone that you can instantly update to this latest and greatest release and that is the Nexus S , the former incarnation of Google’s platform preview vehicle.
So if want Ice Cream Sandwich on your Samsung Nexus S but don't want to wait on the update to push out over the air?
This is for the GSM version only :
*Rename it to update.zip.
*Copy it over to the internal storage on your Nexus S.
*Power off, then hold volume up and power to reboot to the bootloader.
*Using the volume key to navigate, select recovery, then use the power button to confirm
*When you see the warning triangle and arrow, hold the power button and tap volume up. You'll see a menu.
*From the menu, select "apply update from /sdcard", and choose update.zip from the list.
*When finished, choose "reboot system now"
