As Erik said I would like to hear more about the device than your disappoints. I read your other posts about it and I have to say they read like you have something against the iphone itself.
As far as the battery life goes you observed but never investigated a possible cause. Plus - is this your first Apple product? They all have battery issues. In a lot of cases its just running higher end hardware. That pretty screen is gonna suck more juice than a blackberry - its logical to me.
