I just got the newest iphone 3gs. The one that comes stock with 5.0. I downgraded to 4.1 just fine using a custom firmware but I can't get redsn0w to install the 6.15.00 baseband. I got this to work yesterday on a 16 GB one from 5.01 but am having trouble with these new 3gs. Anyone have any suggestions? It'll basically not install the baseband and will leave me with no baseband. Fortunately though it'll let me upgrade to a working 5.01 to start over. Any encountered this?
