I have several iPhones in access (I'm a developer): 2 white iPhones 3G with 16 GB Memory 1 black iPhone 3G with 8 GB Memory 3 iPhones 2G with 8GB memory I discovered that when installing applications, either via iTunes or using Xcode, the 2 white iPhones take 10-20 times the amount of time compared to the other iPhones. All phones with the latest firmware version (I have the effect since v.2.0). This is totally reproduceable, It occurs when connected to my company's iMac and the same at home with my MacBook. Just the 2 white iPhones are so slow! Installing an app on the white ones takes 2-3 minutes while it takes only about 10 seconds with the other iPhones. I don´t know whether the color matters (special series?) or memory size (16 GB). Anybody else with this behaviour?
