the firmware of my iphone 4 is 4.0.1. There are some apps require firmware later than 4.0.1 in order to for those apps working. I knew that the latest firmware is 4.2. However, the jailbreak of firmware 4.2 is not complete yet. So I'm wondering is there any way that I can upgrade my iphone's firmware to 4.1 instead of 4.2?
How to upgrade iphone 4 to specify firmware I want?
