Jailbreak/Unlock/iOS information

Miscellaneous

1) There is no jailbreak (yet) for A5 processor devices (iPad2 & iPhone 4S). It is being worked on. It will be released when it is complete, and tested.

2) There is no untethered jailbreak for iOS5 yet (except for old bootrom 3GS which will always be untethered when Redsn0w is used)

3) Ultrasn0w is not (yet) compatible with 5.0.1

4) There is no software or hardware unlock for baseband 4.11.xx.

There is no method to downgrade a baseband.

Software unlocks are probably a thing of the past, seven new basebands have come and gone without any exploits to software unlock them. If you require an unlock buy a FUL phone or a used phone which can be unlocked (Hint: Do some research first, many used phones are sold at cheap prices because they CANNOT be unlocked. Buying one without knowing it can be unlocked is a waste of your time & money)

5) Flashing the iPad baseband to newer 3GS phones may kill the cellular radio rendering the phone worthless forever.

6) It is too late to upgrade to 5.0. Apple closed the window.

7) Hashes (SHSH) do not work for iOS5. If you have 4.x.x hashes, you can still downgrade the firmware (not the baseband). Make sure your host file is pointing to Cydia.

8) There is no way to downgrade, get rid of or fix the GPS issues with the iPad baseband. Just like the warnings said, it is forever. If a method should be found to remove it, we will announce it. There is no reason to keep asking post after post.

9) If you want to try jailbreaking but have no idea what you are doing: iClarified.com has tutorials, read the blogposts at the top of each page and read some posts asking about problems similar to your issue.

If you post asking for a jailbreak or unlock, asking how long must I wait, complaining that you updated and now cannot jailbreak or unlock, demanding to know when a jailbreak or unlock will be released, or post a question claiming immediate entitlement for a jailbreak or unlock or any such similar unnecessary question, your post will likely just get deleted.
The hackers are working on these tools.
We get these tools for free, so show some gratitude and patience.
