The iPhone Dev Team released an update to ultrasn0w (Version 0.9) and the update fixed a majority of problems seen by ultrasn0w users but you may still see a few problems here and there…

Problems you may see include:

• Unusual battery depletion is almost always caused by people choosing to “Restore from backup” instead of “Setup as new iPhone” when iTunes asks you. This isn’t caused by either the jailbreak or the unlock, but it’s a common 3.0 snafu. The fix is to just re-run the official 3.0 restore and choose “Setup as new” this time. Your music and apps and all that will still be synced, but you’ll get rid of any conflicting wifi, bluetooth, or carrier settings. Then just re-run redsn0w and install ultrasn0w.
• Remember, ultrasn0w works with hacktivated phones too, but don’t outsmart redsn0w into thinking you don’t need hacktivation! If you don’t plan on using an official sim, don’t activate via iTunes with such a sim. Just keep your unofficial sim at all times and let redsn0w and ultrasn0w handle hacktivation
• T-Mobile in the USA doesn’t use the 3G frequencies that the iPhones support, so turn off 3G in Settings->General->Network. (Some T-Mobile territories gracefully hand down to Edge mode, but most do not).
• Certain unofficial plans have limitations on whether you can make calls and use data at the same time. That’s not unlock-related.
• Some people have installed previous versions of ultrasn0w using non-standard techniques. While the ultrasn0w 0.9 update should have removed all previous versions of ultrasn0w, these users may have outsmarted our removal. So make sure you don’t still see /usr/bin/ultrasn0w present if you’re at ultrasn0w 0.9 (which doesn’t have such a binary anymore).
• If you don’t need or plan to update to ultrasn0w 0.9 from a previous version, you can avoid having that red badge over Cydia by removing repo666 as a Cydia source. Don’t worry, you can always add it back later :) If you follow us on twitter you’ll be advised of any new updates anyway.

Can’t wait for the iPhone Dev Team to update their tools for the iPhone 3GS? Well, George Hotz (aka Geohot) has released a very simple application called purplera1n to jailbreak your iPhone 3G S! Both Mac OS X and the Windows application have very similar interfaces so this tutorial will work for both operating systems (Windows is being used in this tutorial). Before we begin, some important notes worth mentioning:

• This one is only for iPhone 3GS users. iPhone and iPhone 3G users use this tutorial
• Make sure you’re running firmware 3.0 (If you’re not sure then you most likely do have iPhone OS 3.0)
• Jailbreak apps like WinterBoard, VOiPOver3G etc don’t seem to be working on iPhone 3GS, so you might have to wait for the developers to release updated version of the jailbreak apps
• Use at your own risk. Please pre-read before attempting anything so you know what you’re getting yourself into ahead of time.

Lets begin:
1. Download purplera1n HERE – for Mac OS X or HERE – for Windows
2. Once you have it downloaded, double click the .exe that you downloaded (if on Windows). If on Mac OS X double click the .zip and it should unzip and then double click the purplera1n.app icon to launch the application.

Apple has posted up an Online iPhone 3GS availability database for people to see if the iPhone 3GS is available at their local retail store. This comes extremely handy if you’ve been visiting the Apple store day after day trying to get your hands on an iPhone 3G S but it always seems to be sold out, this will put an end to that.

Now, you don’t need to waste precious petrol to an Apple store and come back home empty handed. Visit the source link to get to the database.

Well, I know many of you have been waiting for this news, so here it is: iPhone Dev Team has found out that 24kpwn, the same exploit used to crack open into the iPod Touch 2G, lives in the iPhone 3GS bootrom. That means the iPhone Dev Team can apply the same technique that they use to jailbreak and unlock on their current redsn0w tools. The baseband is also exploitable with ultrasn0w. Awesome news, ey?

From iPhone Dev Team:

Important: Apple has not given up on the cat&mouse game, and in fact there are challenging aspects of the 3GS jailbreak that aren’t in the other devices. It’ll take some time to work these into our tools, but the fundamental weaknesses are there: The bootrom is exploitable via 24Kpwn, and the baseband is exploitable via ultrasn0w. (And just like with the 3G, ultrasn0w for 3GS requires that you not update your baseband when Apple comes out with new firmware.)

If you would like to know the technical notes, from the iPhone Dev Team, on where the 24Kpwn exploit is in the 3GS visit here

Now it’s time to wait for the iPhone Dev Team develop and release the tools for users to use and jailbreak and/or unlock their iPhone 3GS’

Apple announced that they sold over 1 million iPhone 3G S models over this past weekend.The press release includes a quote from the one and only, Steve Jobs:

“Customers are voting and the iPhone is winning,” said Steve Jobs, Apple’s CEO. “With over 50,000 applications available from Apple’s revolutionary App Store, iPhone momentum is stronger than ever.”

In addition, Apple also reports that six million customers have downloaded the new iPhone 3.0 software which works on the existing 40 million iPhone and iPod touch models.

T-Mobile.nl has posted some technical specs about the iPhone 3G S revealing that the newest iPhone carries a 600 MHz processor and 256MB of RAM. A nice bump in processor power from the iPhone 3G.

The iPhone 3G had a 412mhz processor while the iPod Touch had a 532mhz processor, until now, the 2nd generation iPod Touch was the fastest device by a good margin on the lineup but the iPhone 3G S has changed that. The previous generation models have 128MB of ram while the iPhone 3G S has a whopping 256MB of ram, so, the new device offers twice as much of RAM. The processor/ram information seems to confirm many details that were first revealed in a Chinese forum post.

The new iPhone is also believed to use the new PowerVR SGX graphics processing unit which provides support for OpenGL ES 2.0. This notably improved performance may require developers to support these multiple device capabilities within their apps.

For those interested in more of a technical analysis, Anandtech offers a detailed breakdown of the new iPhone’s processor and GPU, according to their sources.

Although unannounced, the iPhone 3GS uses (again) a Samsung SoC but this time instead of the ARM11 + MBX-Lite combo it’s got a Cortex A8 and PowerVR SGX; just like the Pre.

Update: If you currently have an iPhone on a contract then you will not be eligible for a standard iPhone upgrade – bummer. You will, however, be eligible for a full retail price upgrade (Prices below).

• $499.00USD — 8GB iPhone 3G (black)
