The iPhone Dev Team had released a beta version of the untethered jailbreak solution for iOS 4.2 yesterday. And from what we hear now, the process has not gone smoothly for a number of users. If you are yet to jailbreak your device, you may want to check out the issues that one can anticipate while jailbreaking with this beta software
- iPod app on iPhone 4 and iPad may not work
- YouTube app on your iDevice may stop working
- Your iPhone, iPod Touch or iPad may face incompatibility with AirPlay
- Applications may crash randomly
- Videos from camera roll may not play smoothly
Besides this, the iPhone Dev team has also outlined a number of other known bugs and have also noted that Bluetooth has been disabled for the time being. What all this means is that unless you are a seasoned developer who can manage these hiccups, this jailbreak is not for you. You may be advised to wait for some more time until a more stable release is developed.
