One issue frequently occurring is accidentally upgrading of iOS versions. As with any other software the best option is almost always to have the newest version.
But this isn't necessarily so in the iOS world, especially if you are interested in the jailbreak and the unlock.
Many users have had the nightmarish experience of connecting their iOS device to iTunes and after choosing the wrong option seeing how their previously jailbroken device is upgrading its firmware.If you are one of such users there is now a tool that can help you with this problem.
Recovery Guard is an app that will solve this problem for you. This small app will tweak iTunes so that it perceives that your iOS device is already updated to the last firmware version. When you successfully install it you wont need to worry about this any more.
If you would like to get this solution you only need to install it through Cydia. Of course you will need to jailbreak your device previously.
Tap Cydia and add this repository http://cydia.pushfix.info
When you add this source you will only need to choose refresh and find Recovery Guard. Simple yet powerful, as always with many Cydia apps. No need to worry about those frequent updates any more. Update only when you want and how you want.
Yet another reason to jailbreak and get Cydia.
Recovery Guard works for iPad , iPhone, and iPod touch. Highly recommended for all you jailbreakers and unlockers.
We wrote previously wrote about the release of the GreenPois0n untethered jailbreak for the iPhone 3G, iPhone 3GS iphone 4, iPod Touch and iPad with the new 4.2.1 firmware.
Although some bugs were already encountered, greenpois0n brought a great improvement in the jailbreaking area and a huge advance for all users in need of the jailbreak and unlock.
But until yet one device was still not supported. The Apple TV 2G was not yet jailbroken with GreenPois0n.
Luckily things are changing in a good direction. The group known as the Chronic Dev Team has acknowledged that they are working on a new jailbreak tool for the Apple TV. They expect to release the new version of the GreenPois0n and that it will enable untethered jailbreak for the Apple TV with 4.2.1 firmware.
One member of the group known as p0sixninja, said that they have a member nicknamed nitoTV who has almost finished the work on jailbreaking Apple TV. Also the readme file in GreenPois0n was changed and the notion of support for Apple TV was inserted.
Here is a @p0sixninja tweet about this:
"Starting on rc6 now, including apple tv support! nitotv has already done most of the work."
Chronic Dev team has not reveled when will the new GreenPois0n version be available, but the good thing is that they are actually working on it and having some great progress.
So we are still waiting for the untethered jailbreak for Apple TV.
It is best to wait for this jailbreak, but if instead you want to use a tethered jailbreak you can do so with the GreenPois0n RC5 on Windows and OSX.
