For those of you who couldn’t make it to the event, and want to relive the unveiling of iPhone 4 as was seen by WWDC 10 attendees present that day in Moscone Center. Apple has uploaded the entire keynote address on both their official website, and on their YouTube channel so that you don’t miss some of the most important announcements by Apple in recent times.

Yes you read that right ! AppSync for iOS 4.0 (formerly iPhone OS 4) is now available for all those of you who have managed to jailbreak your iPhones and iPod touches. For those of you who don’t know, AppSync patches MobileInstallation file on iOS which is needed in order to install .ipa files manually without using iTunes.

Remember that scoop on American Beauty director Sam Mendes directing commercial for Apple iPhone 4? Well that rumor was true after all. Apple today at WWDC 10 showed off the new iPhone 4 with iOS 4 commercial which features video calling via iChat, along with 3.5’’ OLED screen, 960×640 pixel screen resolution, 5 megapixel camera with Xenon flash and lots more.

Apple today has finally released the very final version of iPhone OS 4 (now renamed to iOS 4.0), along with SDK for iPhone 3G, iPhone 3GS and iPod touch 2G/3G. Members enrolled in the iPhone Developer Standard or Enterprise program can access the bits right now, while the public will get it via the latest version of iTunes soon.

We have been hearing about this one aren’t we? but what we have now is final confirmation. According to the member of iPhone Dev Team, full carrier unlocks for iPhone OS 3.1.3, and iPhone OS 4.0 will be released this month once Apple has released both the final version of iPhone OS 4, and the next iPhone 4G / HD.

The title says it all. The popular unlocking tool for iPhone 3GS, 05.11.07 baseband on iPhone 3.1.3/3.1.2 has been successfully ported to work with the latest iPhone OS 4 Beta 4. This port is based on the binaries provided by msft.guy and the original blacksn0w unlock by Geohot.

We are not sure if this is a bug or a feature but if you try to push the power/sleep button for three times in a row on the lockscreen, the iPhone goes right into flashlight mode showing bright white screen. I have also tested this and it appears to be working on iPhone OS 4 Beta 4.

There is a new modified version of PwnageTool floating around in the wild which promises to jailbreak iPhone 3GS on iPhone OS 4 Beta without upgrading the baseband. The creators of the original PwnageTool has confirmed that this version has been modified and redistributed without their permission, and most importantly, it doesn’t patches some important files which are required for the ultrasn0w unlock to work properly.

The latest Beta 4 of iPhone OS 4.0 packs 25 new non-distracting wallpapers which goes really well with the new “Homescreen Wallpaper” feature in OS 4. If you don’t have access to iPhone 4.0 Beta and want to have these on your iPhone, simply download them and follow the instructions below to sync it with your iPhone and iPod touch.

Apple has made iPhone OS 4 Beta 4 available for developers at the Apple Dev Center portal. This new Beta brings lots of cool new features over the last Beta 3 release. Here’s a list of all the features new in iPhone OS 4 Beta 4.

A group of hackers are working on bringing iPhone OS 4 over to the original iPhone EDGE (aka iPhone 2G) which was released back in 2007. Due to low memory and slower processing power, Apple decided to cut further upgrade support path for iPhone 2G in OS 4. The original iPhone EDGE users enjoyed all the firmware upgrades for free up to iPhone OS 3.1.3.

Apple enthusiast site 9to5mac has managed to grab a screenshot from the latest version of iPhone OS 4, which shows a notification popping up in landscape view. While this is likely done in an error, there is still a remote possibility of Apple bringing such support to iPhone. After all, iPhone 3.2 for iPad supports landscape view, then why not on iPhone and iPod touch?
