Disclaimer

There are some things you should know before you perform anything on this site. There is some minor risk involved here. In a worst case scenario you simply restore your iPhone using iTunes and your phone will be back to normal. Doing this will cause you to lose your jailbreak and / or unlock, and perhaps for some time.

• I don't provide technical support. I don't have that kind of free time.
• You potentially risk voiding your warranty (if you can't restore your iPhone to stock firmware).
• Any modifications you perform on your iPhone, including bypassing activation, jailbreaking and unlocking, could be reset (or the option to rejailbreak or unlock blocked) if you should install a firmware update provided by Apple. It is usually just a matter of re-doing everything you previously did to get your iPhone back the way you had it.
• Read the instructions in their entirety. If you can't follow directions, the potential is there for damage (only in extreme cases) to occur to your iPhone requiring a replacement that will most likely be paid for by you.
• I'm not responsible for your results if they are less than what you expected. You assume all risks. I recommend seeking help in iPhone hacking forums or in the various IRC channels. The tutorials I create record the exact procedure I used on my iPhone.
• If you have not activated your iPhone via one of the official cell phone providers (AT&T, Sprint, Verizon, et cetera), and do not pay them for your cellular phone service, then you will lack the ability to use visual voicemail and possibly FaceTime.
• Jailbreaks and unlocks may have bugs in them causing undesirable side effects that have yet to be discovered. Sometimes these problems are solved when the programs are updated. I try to document widespread issues, but can't document everything.
