I keep hearing that updates will fix the dropped calls issue but mine never gets better. I try to have 3G turned of as much as possible as the phone wont hold a call longer than 30 seconds or so on 3G. Have returned it to VF and got another iPhone and it does the same. I have a N95 and it does the same. I feel its a VF issue but they will never own up to it, they just keep saying 3G is very week on the Ponsonby area. So who knows hopefully one day 3G will work. I have given up moaning about it and just have it switched off unless trying to surf the net but even then its fairly tempermental.
