Well, I've downloaded KIES but when I try to upgrade it, it just errors. I bought it second hand from CEX, although they do offer a one year warranty - I'm not sure it would go as far as upgrading the software for me.
I'm worried now - I checked her usage and she racked up 61p in the first day - it doesn't sound like much, but I'm not paying £18 a month when we have a perfectly good wi-fi at home. It must flit between wi-fi and 3G.
Under mobile network settings I can choose between GSM/WCDMA (auto mode) or GSM only or WCDMA only.
What does that mean? I have turned her wi-fi off completely, selected GSM only, and now it says E on the display.
