Xperia go, sola and U: SI number list now live for ICS update

by XB on 4th October 2012

in Android, Firmware, Xperia go, Xperia sola, Xperia U

The Android 4.0.4 Ice Cream Sandwich firmware update started rolling out for the Xperia go, Xperia sola and Xperia U over the last few days. As always, the firmware will be made available to each country & carrier over the next few weeks. If you have avoided flashing your handset to the latest firmware and are waiting patiently in the wings for the update to arrive you’ll be glad to hear that Sony Mobile has just released the SI number list for each handset.

The SI number of each Xperia handset shows which country and carrier that the mobile belongs to. As Sony Mobile releases firmware for that SI number, they will update the list. The SI number is normally available behind the battery, once you’ve located it, hit the links below to find out if your update is live.

    What happens if i buy Xperia from Hong Kong and move to UK, will the update firmware be compatible once i’ve updated in the UK? Not sure if there will be complications. Can anyone shed any light on this?

  • Xperia Go

    1264-6838. Still waiting I guess.

  • Anonymous

    1261-4527 :( None yet.

  • There will be no complications! You will download the update which is for your SI – doesnt matter in which country you update your phone!

    Thank you Mathias, so soon as the Hong Kong SI gets released i can update? or do i have to wait for the UK version? A bit confused at what region time of release I will get to update, but I’m glad at least i will get the update eventually, I hope so anyway.

  • sab

    when is it out in the uk !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  • You bought a phone. This phone has a number: The SI number. This number is important for the update, because different SI’s get the update at a different time. So that means: If you buy a phone with an Hong Kong SI you will get the update when all the Hong Kong devices get it – doeant matter if in that moment you are in London, New York, Shanghai, Sydney or Rome. With your phone you HAVE TO WAIT UNTIL HONG KONG GETS THE UPDATE. Sooner or later I’m sure you will get it!

  • Cory

    oh I see, thank you Mathias, i understand now. cool

  • Xperia U

    i’ve waiting for a real looooooooooog time
    1261-5183 :( still waiting

  • Marius

    Couldn’t wait, it was really getting on my nerves.. Flashed this French unbranded ST25i version. Takes few minutes ant very easy to do with Flashtool. Phone seems to be snappier, but on the other hand seems kinda laggy just after waking from advanced power saving mode. Screen rotation is name, double language suggestion mode and other features youll discover. Overall, worth updating, not worth waiting :)

  • Jono

    Got my Xperia U ST25i update 4 days ago using Sony PC Companion.
    It ran like a turtle. Everything was lagging, slow and the phone was too overloaded to respond to half my keypresses.

    A friend told me to download “Sony Update Service” which flashes the phone from scratch.
    This worked a treat. Everything is running well now.

  • juhae

    ICS, XPERIA U: I had to make factory reset (total wipe). Somehow memory stayed around 20-30 Mb even after memory cleaning operations.

    So 512 Mb and less may not be enough to run a lot of aplications. Or aplication which tends to reserve memory.

    Depends what kind of aplications there is in the phone. Widgets, Social or News.etc.

  • Dani

    Yup ..
