Bluetooth, Music and iTunes Stuck After Jailbreaking iOS 4.2.1 with Redsn0w 0.9.7b1 [Warning]

Early today Dev-Team has announced the untethered jailbreak for iOS 4.2.1 on iPhone 4, iPod touch 4G and iPad, and then we followed it by the step by step guide to use the redsn0w 0.9.7b1 jailbreak,
but it looks like that we are in dire need of beta 2 for this version as some of our reader who jailbroke their devices using beta 1, have noted some errors with Bluetooth, playing music and iTunes.

This video will show you these errors clearly, you will note that the iPod touch will restart after trying to run iTunes, also the music doesn't work and a frozen Blutooth, only apps and Cydia are working well

For now we expect that Dev-Team are recording bugs as much as possible to release a new beta version free of bugs. Check your Bluetooth, mucic and iTunes and let me know how the new jailbreak going with you.
