Hi, i upgraded my i9000 (Galaxy S) via Keis a good few months back only for it to have problems with wifi, freezing and being generally slow. It went back to Samsung and when it came back all they had done was factory reset and tested it. That was about 2 months ago, since then its been gradually running slow again and still having wireless problems. Ive done several factory resets to no avail. Im done with Gingerbread and now want to revert back to Froyo as this was far more stable and reliable. Does anyone know how to do this? I really do not want to send this back to Samsung as im not convinced that they will do what i asked! The unit is a brand-free handset from Carphone Warehouse. Current Build GINGERBREAD XXJVO 2 6 35 7 i9000XXJVO CL182937se infra@SEP 51 #2 and Firmware 2.3.3 - whatever that all means!! (dots and dshes removed in order to post here) Any help appreciated! Thanks. Geoff.
