So I went into an Apple store yesterday to play around with the Iphone 4 and it just so happned the store I was in had the phone in stock. After playing with it for about 20 min I decided to purchase one. I was obviously all excited on my drive home. Once I get there and plug in my phone into my Macbook I get an error saying my operatin system needs to be version 10.5.8 or higher. I'm currently running 10.4.11. So now I have to update my software which Apple said would cost me $169 (I don't feel like spending that cash so I will be returning the phone today). As far as the antenna problem, I had my 3gs and 4g side by side all night and morning. The 3gs definitely has more bars in almost all locations. With that said I never had a dropped calls or no service to make a call with either phone. The bars on the 4G fluctuate A LOT more than the 3gs but it still does the job. The build week is 30 on the Iphone4 and when I touch the bottom left corner I do lose 1 to 2 bars right away. This message is in no means trying to bash the iphone4, it's just simply an update for those guys/girls that are still on the fence on purchasing one.
