planetbeing from the dev-team did a live showing of ultrasn0w on the 3GS, showing you that Cydia works perfectly and that the unlock is succesful. Great news for me as I have T-Mobile. Now I just need to get my hands on a 3GS!
When the official 3.1 beta comes up make sure you do not upgrade to it, you will lose your unlock and possibly lose it forever. Apple is closing the loophole that the dev found to make the unlock. The dev-team will release tools that will allow you to safely unlock to make sure your device stays unlocked and jailbroken
If you have any questions and you've tried ask the dev team but maybe they don't answer back you can tweet me as well. I will try to answer your question to the best of my ability. Want a quick answer? email me at irockish@hotmail.com That goes directly to my iPhone
If you are a ultrasn0w user and before you get excited please note that you should not upgrade. Why? 3.1 already comes with ways to stop ultrasn0w just as @musclenerd said it would.
So if your planning on buying a 3GS, do it NOW. 3.1 is sure to fix the holes that the dev-team broke through to unlock the iPhone "3G".
So what comes in the new firmware? The following: - Video editing now gives you the option to trim your clip then “Save as copy…” rather then writing over and replacing the original clip. - Voice Control now works over Bluetooth - The iPhone now vibrates when moving icons - Updated AT&T profile to 4.2 - Updated modem firmware to 5.08.01 (*this is what will kill ultrasn0w) - Improvements to OpenGL and Quartz. - APIs to allow third party apps to access videos and edit them. New tools for the developers - MMS buttons are back in the Messages app for AT&T customers but still don’t work. I wonder when later this summer is going to be? - Copy & Paste functions also work in the address book as well as in the numeric keypad of the phone application. Nice little improvement, it did work when you would go into the contact and hit edit to get the number now allows you to highlight the number and copy will come up - Videos can be saved from e-mail attachments and stored in your photo album. - Find My iPhone feature, still only for MobileMe users, the audio alert Blasts at full volume regardless of what the ringer volume is set to. - Does not fix the pitch noise for iPhone 3GS users that were experiencing this problem.
I guess with all these features, that is why it's 3.1, instead of 3.0.1 which probably would've just been made to kill Ultra, as I'm sure is Apple's main concern rather than getting MMS out to it's customers.
iPhone 3G Owners can now rejoice everywhere as ultrasn0w is now officially available. BIG THANK YOU goes out to the Dev-Team for all their hard work and focus on trying to get it out ASAP for us. Make sure you check their blog, and follow them on Twitter!
I'll post a vid tomorrow, joining the other million that will be up on how to unlock the iPhone, its pretty simple if you have it jailbroken just follow these instructions straight from the dev team themselves.
