Can anyone tell me how to install 3 of these parts to my iPhone 3g? I’m clueless but want to try it out. I’m already on a developers list to be able to do this.

Put all the parts in a folder.
Right click on any of them
n extract.

you need Winrar to extract these files

If you dont know how to extract .rar files and install, how are you possibly on the developer list.

Anyway… you need to download winrar… have all 3 files in the same location. open anyone of them with winrar and extract. it will place all 3 files into 1 .ipsw file. then you open itunes and attach your iphone. Hold shift and left click restore then browse to the location of the .ipsw file. open it.
