Free iPhone OS 3.0 Software update – Cool but Deactivate PIN Before Upgrade!

The free iPhone OS 3.0 Software update includes some great new features and really good stuff, including “Cut & Paste” and “Internet tethering” (modem) so that you don’t need a Wi-Fi hotspot to surf the web from your computer – But it has one fatal flaw that O2 customers need to be aware of… If anyone is thinking of the iPhone OS 3.0 Software update… I recommend Unlocking your O2 SIM card and leaving it PIN free before attempting the update! Download works ok but if the PIN is active it will prevent phone from activating after upgrade ! I know… I learned the hard way!!!
To deactivated PIN, go to Settings > Phone > SIM PIN > Switc to OFF. Upgrade should work ok then…
