Where can I find stock or custom ROMs for my Android device?
I did the whole exercise and rooted my Swiss Sunrise 2.3.4 Galaxy S II ending up installing CM9 and the ICS 4.0.3 preview without TouchWiz shown and described here:

I do not have a backup of the original stock rom from Sunrise for Switzerland and with this new version I cannot install home banking application (it's restricted for swiss devices and for OS version) neither can I install the new Chrome Beta for ICS because it tells me country is wrong.
where can I find a step-by-step guide on where/how to find the original rom and put it back possibly also unrooting so to bring the phone to its original state/configuration? Thanks!!
