Here’s a short video of yellowsn0w in action. It works much faster than the first version and all T-Mobile USA customers should be happy! Check the iphone-dev team blog for the source URLs to the Cydia / Installer repos.

yellowsn0w 0.9.5 beta demonstration from theiphoneproject on Vimeo.

Let us know if it worked for you!  If you guys are still having trouble, the amazing iphone-dev team have setup a bug reporter/tracker system. It can be accessed here.

Quick Update:

Everytime I reboot the SIM isn’t recognized (it just searches for network).  If you turn airplane mode ON and then off (Settings > Airplane Mode: ON), it will start working.

For those of you that are using T-Mobile in the US and are having trouble getting service using yellowsn0w, we found a tip made by the commenter “Richie Rich” on the iphone-dev blog. I personally tried this after some mishaps and made it work. I’m using T-Mobile in Chicago and it definitely saved me some waiting around for a different or newer solution.

And again, yellowsn0w is a beta product. The iphone-dev team guarentee jack squat except pure “l337ness”.

Here’s a few steps if you can’t get it to work:

1. After installing yellowsn0w through Cydia, keep your T-Mobile SIM inserted.
2. You must reset the network settings.  This is probably the most important step.
3. Reboot your iPhone.
4. Turn Airplane mode on (Settings > Airplane mode: ON).  Turn it off after a couple of seconds.
5. You should see “searching” near the top, and this is when the glory happens.

Let us know if this worked for you either in the US or anywhere else in the world.  Keep in mind that T-Mobile USA uses a different 3G network than AT&T, so US iPhone 3G WILL NOT work on the T-Mobile 3G network.  You must DISABLE 3G network from the Settings pane.

Welcome everyone back to the new and improved theiphoneproject.  We have had several advancements in our layout, downloads sections, and guides.  The key enhancement is our layout - it is much less cluttered and easier to find things.  We have also (thanks to iphone-dev team) switched over to IntenseDebate’s amazing commenting system.  It is implemented all across the board - so anything you feel the need to comment on, please do.  We love to read any and all feedback regarding our content and how to improve it.

Key changes

• Downloads are vastly improved.  We now have categories - linking to unlocking software, bootloaders, and firmware files.  We have added release dates for every single iPhone firmware.  We also have descriptions on each file and they link to the proper guide (if applicable).  There are many notes in the downloads section.  Please note this:  we do not reccomend downgrading past 2.0.  All of our guides are updated and we are continuing to update them everyday.
• Guides have been updated.  We also used IntenseDebate for commenting on our guides.  It really adds a personal feel to the system.  Hopefully everyone can take advantage of this and we will be able to have the best damn iPhone source on the net!  The actual “Guide” link at the top leads you to a page where you can select your operating system (Windows, Mac, Linux) and then select your device - and then we will list our guides.  We are still working on the best scenarios for this section.  Any feedback is welcome.
• Style - we simplified everything.  Joomla is no more.  We apologize for the inconvenience if it’s what you liked, but we truly believe our new user interface is simple and straight to the point.

Thank you all for the continued support.  We look forward to hearing feedback and improving our site to suite your needs.
