Tonight has been released the first working Android Ice Cream Sandwich build for the Samsung Nexus S. The ROM is surprisingly stable, and the user experience is much smoother than the earlier SDK port builds. Indeed, these versions were unusable in my opinion.
Almost everything seems to work except the USB connection (I will have to investigate on that using the logs. One quick remark though, if the Wi-Fi connection fails, add your network manually and it should work perfectly.
I won’t make you wait any longer, you can download it from the XDA Forum.
Update: A patch for the Wi-Fi issue has been released last night, you can download it from here.
Latest Update: The V2 has just been released by kwiboo, it is available on the official topic.
After flashing, do not forget to apply the Gallery/Calendar patch. Also if you use an Echange account, you have to re-install the Email.apk available from the /system/app folder (use any root explorer to access it).
For a considerable performance gain, install the excellent Franco’s Kernel.
