Here’s what the Dev Team has to say about this release:
This is a beta release of redsn0w targeted at developers of jail broken apps. It uses the same pwnage2 DFU-mode exploit that we’ve been using since the 2.x days. Nothing new is revealed to Apple, and it’s not applicable to the iPad. Don’t go near it if you use yellowsn0w, ultrasn0w, or blacksn0w.
Important Notes:
Please note that redsn0w 0.9.5 beta is only available for Mac OS X and works with iPhone 3G. In case you want to try iPhone OS 4 beta, download the appropriate firmware file from Apple, which will require UDID registration. There are many methods available to get iPhone OS 4 beta file, but it’s difficult to predict their success.
In case you have upgraded to iPhone OS 4 beta, you can still downgrade to iPhone 3.1.2 or iPhone 3.1.3 firmware’s. However, your iPhone’s baseband will get updated to 05.13.03.
