Run RedSn0w and point it at the 4.0 IPSW. (Yes – point it at the 4.0 IPSW even though you're at 4.0.2). This will also hacktivate your iPhone3G at 4.0.1 if you haven't already been activated by iTunes.
If you need a carrier unlock - install ultrasn0w in Cydia (add repository http://repo666.ultrasn0w.com). For T-Mobile in the USA remember to turn off 3G mode in Settings→General→Network.
Some users say that they have problems, while trying to use the JailbreakMe.com service. They simply can not browse the site! We decided to solve this issue, so you can unlock iPod touches, iPads and iPhones. Follow these instructions to achieve a positive result!
Step 1: Instead of typing http://www.jailbreakme.com, enter http://jailbreakme.com/index.html, it will take you directly to the site that really works.
Step 2: If the above does not work, use the Canadian extension as follows http://www.jailbreakme.ca. App Advice claims that it is a mirror redirecting you to the current website version.
In addition, remember that JailbreakMe will work only on your Apple devices, running on iOS 3.2.1/iOS 4.0.1 or below.
The recently released application MiTime for the iPhone 4 fixes and activates FaceTime on unlocked iPhone 4s that run on T-Mobile USA or other unofficial unsupported carriers. According to the MiTime’s description, it should work with almost any carrier in the world. You should be able to receive international SMS messages to activate FaceTime via MiTime.
The application MiTime sends two international SMS messages for activation, so it can not be free. Thus, until there is no other way to activate FaceTime on unlocked iPhone 4s, this is the only way with an affordable price.
The U.S. Patent and Trademark Office revealed a patent application from Apple entitled "Systems and Methods for Identifying Unauthorized Users of an Electronic Device." The invention describes methods to identify users through a picture, the sound of their voice, or even their heartbeat.
"The photograph, recording, or heartbeat can be compared to a photograph, recording or heartbeat of authorized users of the electronic device to determine whether they match," the application reads. "If they do not match, the current user can be detected as an unauthorized user."
If an unauthorized user were to attempt to access an iPhone or another device, the owner of the handset could be notified via a phone call, text message or e-mail. It could send the owner - or the police - a picture of the unauthorized user, or other information specific to the potential thief.
The handset could recognize an unauthorized user if they do certain uncharacteristic activities with the phone, such as hacking, jailbreaking, unlocking, or removing a SIM card.

Social Bicycles - a bike sharing system with a twist – plans to start using an iPhone application, the system allows users to drop off, locate, and borrow a bike nearly anywhere. The bikes are equipped with a GPS device which is locked to one of the wheels, and when the bike is locked, it's locatable using the application, so that someone can borrow it; when it's in use and unlocked, it doesn't appear in the app. The real upside to Social Bicycles is that the regular infrastructure required for bike lending systems are unnecessary, which can make lending much cheaper.
As you might know iPhone 4 is available unlocked in many different countries around the globe. The prices vary a lot.
Filip Chudzinski from Germany put together a comparative chart with iPhone 4 prices. As you can see below it can often be well worth it to order your iPhone 4 in a different country (you’ll need an intermediary), or even just going across the border.
Update: some users report that this chart contains errors, so do not forget to check everything before traveling around the globe.

MuscleNerd, hacker from DevTeam, commented via twitter on recent rumors that universal jailbreak (all iPhones and all firmwares, including iPhone 4 and iOS 4.0.1) will be released today. The basic answer is no, there will be no jailbreak today.
Not to make it a daily thing, but since somehow people thought it would be today: the new JB+unlock won't be out today
(there are issues with important apps like Facetime that need to be figured out...no sense releasing a half-broken JB)
Jay Freeman, better known as Saurik, the creator of Cydia, was interviewed by the home radio Make It Work. He speaks about the history and the future of the iPhone jailbreak.
Saurik describes the origins of Jailbreak and Unlock for the very first model of the iPhone. Jay explains that initially there were two important things to do with the iPhone 2G - to use other carrier than AT&T and to install any application.
He continues discussing the main applications from Cydia. Cycorder was the first to allow video recording, and Winterboard was the only one that allowed users to change the graphical interface of the iPhone. He also speaks about Comex, the hacker who is currently working with the Dev Team for releasing and Unlock for the iPhone 4. According to Saurik the tool is still not ready to be released to the public due to severe bugs in the code. Here the second part:
