Hi all devs,
We just released a blogpost http://developer.sonyericsson.com/wp/2011/12/15/ice-cream-sandwich-alpha-rom-available-for-unlocked-xperia-phones/ announcing that we have made an ICS alpha ROM available for users with very good tech skills. This means that you should have an unlocked boot loader http://unlockbootloader.sonyericsson.com, and have the knowledge to switch between different ROMs (read our blog post for further disclaimers ; ) ). Also, please note that the released SW is only applicable for Xperia™ arc S, Xperia™ neo V and Xperia™ ray. Xperia™ arc will not work, as it has different partition layouts.

This is the first time we have done an activity like this and I, and all others behind this really value your feedback https://www.surveymonkey.com/s/STRJKQF. The release of the ICS alpha ROM is our way of sharing where we are with the ICS upgrade project. My team at Developer World, also published an article last week outlining the different activities we have to pass before releasing an official ICS ROM http://developer.sonyericsson.com/wp/2011/12/07/ice-cream-sandwich-from-source-code-release-to-software-upgrade/. Looking at that article I would say that we are now in the Bringup phase. You will also quickly see that we have not passed certification and approval phase, since we were not allowed to have the radio module turned on. This means that you can’t make any phone calls or use Wi-Fi. However, I still thought that this will be valuable to the tech community. Youtube video: http://www.youtube.com/watch?v=QoIsNYR7XJ8

What you can do is to test ICS applications early on, and you can also give us feedback on this initiative, and what you think about the ICS alpha ROM. Did it meet your expectations? What things would you wish for. We have a link to a survey in the blog post, where you can submit your feedback. But hey, I can’t promise that we can take care of all requests, as I know you will have plenty… Lastly I believe this release will benefit the custom ROM developers so they can see where we are in our process and how we have solved different things.

Share your opinions!

WOW! This is seriously fantastic! When you first announced you were supporting FXP and made camera libs avaiable, I thought that was amazing. But letting the community try you guys have achieved is so cool! This is the most awesome thing, I have ever seen a company do, seriously!
I have seen something similair before, where devs. make an alpha-release, and already from there, want different oppinions and built from that. Keep involving with the community SE! :)

That's nice, but I have two questions.

The final ICS for Xperia will look different, fresh, right? Becuase this one looks just like Gingerbread.

I noticed on that video, that you have to long press home button to get the list of running apps. Isn't ICS supposed to get rid of the menu button, by making it to work like home long press used to in Gingerbread?

Hmmm what will happen if i flash this to my Play? Not the best idea right?

I wouldn't think this would be a good idea lol.

Anyone read this its inside the "readme" Also, if you unlock the boot loader, you will not be able to download and install the final Ice Cream Sandwich software upgrade from Sony Ericsson.
For additional information on limitations and warranty, please see the Sony Ericsson Unlock boot loader service.

Spot on SE Dev team, you guys are leading the way these days when it comes to the support for the people that people ask what phone to get, as lets be honest everyone ask's there "Geek" friends what phone to get and the love that SE gives to us just goes to show you are a company that really does care what we the users want to see in the products we buy from you.

Share your opinions!

I already did mine through a comment on your blog post.
However, I will repost it here:

First of all, let me congratulate you for the effort and transparency you’re putting into this. This bridge Sony Ericsson is attempting to create in order to involve more experienced or curious consumers and developers is something that greatly makes me proud for picking your products in the first place.

Since you’ve already demonstrated to value our opinion, I hope you’ll consider mine:

Please, consider upgrading the kernel version to 3.0. The 2.6.32 you have on Gingerbread, and by looking at the demo you just posted it will also be on ICS, is severely outdated (October 2009). 2.6.32 was the official version for Froyo whereas 2.6.35 was for Gingerbread and 3.0 is for ICS. Anyone inside the kernel world knows that a great deal of optimizations separate these versions (RCU, CPU scaling, SLAB, MM, PM, …) which have a deep impact on the overall experience.

Sadly to say, Sony Ericsson competitors aren’t keeping themselves on 2.6.32 (all of them advanced to .35 on Gingerbread and probably 3.0 on ICS) and this may cause an undesirable discrepancy in experience not in favor of your products. I also know that this probably means rewriting a few libs or drivers there and there but you can’t deny it will be worth in the end.

In my opinion, the benefits of pushing the kernel version to 3.0 far outweigh the increased delay you may have on releasing ICS (1 month?). Do consider this.
