I have an iPhone 3g with firmware 3.1. It has a modem of 5.11.07 and a bootloader of 5.09. I know it is possible to unlock phones with 5.11.07 and bootloader of 5.08 but I have not heard of anything happening with the 5.09 bootloader. If anyone has any information that could help me about this, you can either respond to this topic or email me at [email protected]. I have been trying to unlock this phone for the longest but have not been able to find much info regarding the 5.09 bootloader. Anyone's help will be appreciated.
