Decided I'd read enough about iPhone OS 3.0 and that I needed it on my iPhone 3G
now!
What a simple process this is this internet world of ours. Found out exact file name of golden version that I needed. Downloaded it from torrent. Installed on iPhone 3G via iTunes. Whole process took less than less than an hour.
Now have iPhone OS 3.0 installed. No data lost. All looks good. Now need to see what the new features are...
