Downgrade from iOS 5.0.1 to 4.3.5

[auptimus]

Hi guys,
I have an iPhone 3GS with iOS 5.0.1. I want to unlock it using the iPad BB, but I keep reading that It may be bricked and the GPS will no longer work. Here are my questions:
- Can I downgrade from 5.0.1 to 4.3.5 (I haven't backed up the previous SHSH blobs of the old version)? I know if I downgrade, SIRI will no longer work on that version.
- If I can downgrade, can I unlock it with sn0wbreeze without upgrading to the iPad BB?

What are my options?
Thanks
Optimus

No, you can't. Your questions have been answered and discussed for too many times. A simple google or forum search will give you an answer.

iPad bb is your only option.
It doesn't matter if you're on 5.0.1 or 4.3.5 the baseband doesn't downgrade, just the firmware does.
And installing the iPad bb is not a good idea.

Hi,
Ok for the input. I know installing the ipad bb is not a good idea. Still waiting for a fix to install a different bb on the iphone 3GS on 5.0.1.
