UltraSn0w works same as YellowSn0w. About UltraSn0w application is a small daemon that is launched on boot. It injects the payload at boot and also whenever there is a baseband reset. You won’t notice anything about it other than that your third-party sim now works. It’s a small program and unobtrusive. The UltraSn0w unlock will be released on Friday 19th along with iPhone 3G S and will be applied in the same manner as the previous yellowsn0w unlock. The procedure will work on the 4.26.08 baseband version so all those who accidentally updated to the latest baseband will be able to regain their unlock. And anyone at 3.0 FW or below will be able to use it.

Things are completely changed and Apple is going strict and strict, trying best possible methods to keep Devs . According to GeoHot Apple added a new tag to the img3 format called ECID. The ECID is unique to each phone, and is being sigchecked. So no downgrades unless you have a dump of your unique old firmware’s img3. Therefore, iBoot exploits won’t be so useful for tethered JBs, because such exploits will be closed in new FWs. This is bad news… They almost surely won’t authorize downgrades on new phones. They might not even authorize downgrades on older phones. Get a usb dump of a restore to 7A341 if you ever want to go back(which you may need to use exploits). Unless of course it’s broken deeply at the hardware level. Then lol @ Apple.

Geohot has already launched purplera1n.com (Purple Rain) but is hosting nothing but an image as of now. So we can guess at the moment that Purple Rain is the code name of 3G S jailbreaking tool. After Zibree (ZiPhone) Dev Team gets a new competitor. BTW GeoHot is not new but he was less active, now it seems GeoHot is on the way back as he appears. Lets wait n watch this healthy competition between GeoHot and Dev team. GeoHot discovered Ramdisk keys and Musclenerd discovers Vfdecrypt keys and they provided these keys publically available. So finally we can say that after Sn0w get ready for the rain, purple rain.

The new iPhone OS 3.0 adds over a hundred new features including-at friggin’-cut and paste. Here’s how it works: When you double-tap over text, you will get a “cut, copy, and paste” bubble dialog. Double-tap again and a “paste” bubble will appear if there’s anything stored in your clipboard. That’s not all, you can also copy and paste photos. Now you will be able to select photos by tapping the action button, copy them, and paste them in an email, voila, ready to send.

Apple’s newest product let’s you search in mail, ipod and in calendar. These Apple applications have specific search interfaces. The search in Mail doesn’t support the message content yet, but it supports searching in IMAP servers-that gives you an ample time than logging into Gmail.

Thetering. If you are familiar to a camera connected to a laptop, then that’s thetering. But in other way, your iphone connected to your laptop instead, it serves as the modem to access you to the internet.

Now, a much better keyboard. Apple has added the landscape keyboard mode to other applications, like Mail, SMS, and Notes.

Yes, it is also in here, MMS! A big one to send rich content to people without mail-enabled telephones. The MMS function will allow you to include everything, from images to sound to vcards (no word on video, however.)

So, there you go. Apple iphone at it’s best!

With Pwnagetool, you can unlock the Original iPhone (1st Generation), Original iPod touch (1st Generation) and the iPhone 3G. But this tool would not work to unlock the iPhone 3G S which is just released into the market. Soon, Dev team would also release the ultrasn0w which would be the ultimate tool to unlock the latest firmware iPhone version. Here are a few mirror links to download Pwnagetool to unlock the iPhone 3.0 firmware -
