I listened to your podcast. MMS doesn't bother me. I've dowloaded QuickVoice from the Apps store to record sound, it's really easy to use. Michelle and I are going to use the iPhones to record our anecdotal evidence. I am not using the iPhone for voice calls or SMS because I have my own phone for that but I am exploring the Apps. There is a TruPhone App that allows you to use Skype over wi-fi so I am trying to get that working. At the moment I would give it around 80% mainly because of battery life. Yesterday I found that having a Twitter App drains the battery even quicker. Normal usage is one day but with the Twitter App running it went to half a day, which is really poor.
