I have an officially unlocked 3G which I have recently restored to sell it. However, having put in a different SIM to activate the phone, the carrier logo is still stuck on Orange (my old sim) even though I'm using an O2 sim. I did update the carrier settings a while back with a modified IPCC to enable tethering, but I'm surprised the Orange logo is still there - especially when everything has been wiped. Does anyone have any ideas on how to change this to show whatever carrier logo is with the SIM!? Thanks!
