There's no SI in build.prop.

Here you can find list of Xperia U phones, and customisation numbers, chceck your customisation number in build.prop and search it on this list. There's all info about model, for which market it was released, branding etc. Also you ca find your original SI number on the side of phone box alongside IMEI number.

If you have flashed different GB rom, your customisation number has changed.
If you want to get update for your ofiicial firmware, you have to know what was your customisation number before flashing .184 which you get from xda.

ya, sorry the corresponding customization number that goes with the SI number in the build.prop file, thats what I meant.
