If you own T-Mobile’s variant of Samsung Nexus S (i9020t) and don’t want to wait for the official OTA Android 4.0.3 update, you can install it manually. The procedure below will upgrade stock Android 2.3.6 build GRK39F to Android 4.0.3 build IML74K.
With a rooted phone the easiest update process is to use ROM Manager (Download ROM -> Stock Images -> Nexus S 4.0.3).
If you don’t have root, follow these manual steps (if you are new to the update process, check out this slightly outdated, but detailed update guide).
- Download the update package.
- Rename downloaded file to update.zip.
- Copy the update.zip file to the phone’s internal storage.
- Turn the phone off, press and hold Volume Up and Power to boot into the bootloader.
- Using Volume Up/Down select “recovery” and press Power button.
- After the exclamation point in a triangle appears, hold the Power button and press Volume Up.
- Using Volume Up/Down select “apply update from /sdcard” and choose the update.zip.
- After the update process is finished, select “reboot system now” and press Power.
Enjoy!

Can i follow this procedure to update my Samsung Galaxy Y GT-S5360 from Android 2.3.6 to 4.0 ?
The update procedure is the same, but you need to have an update file specifically for Galaxy Y. The link that I included in the first paragraph will work only for Nexus S. I don’t know if Samsung plans to update Galaxy Y to Android 4.0. If they don’t, hopefully CyanogenMod will support it: Samsung Galaxy Y (GT-S5360 / GT-S5363).
