Hi, I was wondering that can I apply patches of Sony Ericsson W850i firmware R1KG0001 on W830i firmware R1KG0001? I couldn't find patches for W830i, however I found loads of patches for W850i, and I was wondering if I could apply those on my W830i, since both the phones are basically the same (ones 3g ones not, both are db2020 though) thanks.
