While there are many third-party iPhone App Stores like Cydia around, the problem with them is that they all require jailbreaking of iPhone, which even though has gone 100 percent legal isn’t something which every iPhone user will do. Comes in OpenAppMkt, a new web-based third-party app store for all iOS based devices which consists of apps, completely written in HTML format. OpenAppMkt runs in browser and installation of apps simply require a simple tap on: “add to home” button.

This is how it looks like:

and here is video, showing OpenAppMkt in action on the iPhone.

Please Note that this is only for Developers

you can find the tutorial to Jailbreak iOS 4.1 Beta 1 here

If you have iPhone 3G (which doesn’t rely on an unlock), or an iPod Touch 2G (non-MC model), then simply follow this guide

Step 1:

Download iOS 4.1 Beta 2 for your version of iPhone and iPod touch.

Step 2:

Update to this latest firmware using the IPSW file you just downloaded via iTunes 9.2

Step 3:

Start Redsn0w 0.9.5b5-5 (download link given below) and point it to iOS 4.0 (Final Version), and not iOS 4.1 firmware file to proceed with the jailbreak.

Redsn0w 0.9.5b5-5 (Windows)

-

Redsn0w 0.9.5b5-5 (Mac)

Step 4:

Now select “Install Cydia” and click “Next”.

Step 5:

Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”.

Step 6:

Connect your device in recovery mode by pressing the Power and buttons continuously.

At this stage you will be presented with a screen where you will have to quickly hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.

Step 7:

Once done, your iPhone will restart automatically and you will find it jailbroken on the latest iOS 4.1 Beta 2 firmware.

**Thanks to the iPhone Dev Team for making this jailbreak possible.

Just a quick heads-up: Sherif Hashim confirmed that baseband 05.14.01 ( and above ) makes ultrasn0w 0.93?s exploit obsolete. iPhone 3G and 3Gs users should stay on iOS 4.0 or 4.0.1 and do not update to future iOS releases, otherwise you won’t be able to unlock your iPhone.
Probably ultrasn0w will be updated in the future or, who knows, new unlocking tools will be released. But for now, just stay away from that update button.

Simply Download the the PwnageTool bundle and then follow the step by step instructions for patching PwnageTool 4.0.1 for iOS 4.0.1. Once you are done with the jailbreak, you can then unlock it using Ultrasn0w 0.93 on any baseband (including 05.13.04 and 05.12.01)

Once again, perform the instructions at your own risk only. I am not responsible if you end up bricking or locking your phone. Only proceed if you are an advanced user, and know what you are doing. Otherwise, wait for the new official tools which would be out soon.

Step 1:

Download PwnageTool 3.1.5 from the download link given here.

Step 2:

Download the latest version of PwnageTool Bundles from msft.guy here and then extract it to your Desktop.

Step 3:

Download iOS 4.0.1 for iPhone 3GS, and iTunes 9.2 for Mac.

Step 4:

Download the updated Cydia bits (data.tar file) from here.

Step 5:

Copy PwnageTool that you downloaded in Step 1 to your desktop. Right click, and then click on “Show Package Contents” as shown in the screenshot below.

Step 6:

Navigate to Contents/Resources/FirmwareBundles/ and pasteiPhone2,1_4.0.1_8A293_bundle.bundle file in this location and then simply close this folder.

Step 7:

Now navigate again to Contents/Resources/CustomPackages/CydiaInstaller.bundle/files/ and paste data.tar file (for Cydia) that you downloaded in Step 4.

Step 8:

Start “Terminal” program on your Mac and run the following commands:

cd desktop

cd PwnageTool.app/Contents/Resources/CustomPackages/CydiaInstaller.bundle/files/

tar -xPvf data.tar

once you are done, close all the open windows.

Step 9:

Now start this patched version of PwnageTool, Select iPhone 3GS as your device and you will now notice that PwnageTool will automatically detect iOS 4.0.1 firmware file as shown in the screenshot below.

Step 10:

Simply follow the steps to create a custom-cooked iOS 4.0.1 firmware file which will preserve your old baseband.

Step 11:

Once the .ipsw file has been created, you will now have to restore your iPhone to this custom firmware 4.0 that you just cooked using PwnageTool 3.1.5 for your iPhone 3GS. Start iTunes 9.2 Click on your phone icon from the sidebar in iTunes. Now press and hold left “alt” (option) button on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release this button.

This will make iTunes prompt you to select the location for your custom firmware 4.0.1 Select that custom .ipsw file and click on “Open”.

Step 12:

This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs the new firmware 4.0.1 on your iPhone. Your iPhone screen at this point will be showing a progress bar indicating installation progress. After the installation is done, iPhone will restart automatically and you should now have a fully jailbroken iPhone 3GS running on iOS 4.0.1

The following step by step guide will help you rollback / downgrade to iOS 4, iPhone 3.1.3 and 3.1.2 from iOS 4.1 Beta as long as you have SHSH blobs saved for the respective firmwares for iPhone 4, iPhone 3GS, iPhone 3G and iPod Touches.

Step 2:

• Hold Power and Home button together for 10 seconds or so.
• Release Power button but keep holding the Home button until your computer recognizes a new USB device.
• iTunes will now recognize your iPhone.
