How to Jailbreak iPhone 3.0.1

Note: You can use these steps for iPhone OS 3.0

The iPhone Dev team released their much awaited software solution earlier to Jailbreak iPhone 3GS OS 3.0 with RedSn0w. However Apple has released 3.0.1 which included the iPhone SMS vulnerability patch recently. So here is a step-by-step guide to jailbreak iPhone 3G(S) using RedSn0w 0.8 (on Windows). For unlocking your iPhone 3G/3GS first jailbreak with following guide, after a successful jailbreak follow our guide on Unlocking iPhone 3GS with UltraSn0w.

After unlocking with Ultrasn0w on 3GS reset your network setting once from Settings->General->Reset->Reset Network settings once. The process is very similar as iPhone 2G, 3G and 3GS jailbreaking.

Download of Interest :
iTunes 8.2: Download here
RedSn0w 0.8: Download here
iPhone 3G Firmware 3.0:Download here
iPhone 3GS Firmware 3.0:Download here

Once you have completes all download then read this guide twice or thrice before doing anything.

Step One : Create a folder on desktop and name it whatever you wants in the following article we named it iPawnage. Now put all your downloaded files in the iPawnage folder. Now connect your iPhone to the computer and launch RedSn0w from iPawnage folder. In the Window click on the browse button to navigate to the iPawnage folder on your desktop and select the 3.0 firmware ipsw.

Step Two : Click the Open button to continue

Step Three : In next Window check the Install Cydia option (remove check on Install Icy) to Jailbreak your iPhone 3G(S).

Step Four :
For iPhone 3G turn off your iPhone but make sure it is still plugged in to USB port. If you satisfies this term then click next to put your iPhone in to DFU mode follow the onscreen instructions as follows Hold the Power button for 3 seconds, Hold the Home and Power buttons for 10 seconds, then release the Power button and continuing holding the Home button until your iPhone is in DFU mode.
For iPhone 3GS Disconnect your iPhone from your computer and turn off it by holding the Power button until 'Slide to Power Off' appears, and the slide to power off. Wait five seconds after the device is fully powered down. While holding down the the Home button, plug the USB cable into the device. KEEP holding down Home until the Apple logo disappears.

Step Five : If all goes well means you put your iPhone in DFU mode successfully then the following screen will appear otherwise you will be prompted to do from Step Four.

Step Six : That’s it after 5 to 8 minute of process it will reboot. After the reboot, you will see Cydia on your springboard. Now your have a Jailbreaked iPhone on your hand.

Unlock iPhone 3.0.1

1. Once your iPhone is jailbroken, open Cydia.
2. Add repo666.ultrasn0w.com to your sources
3. Install ultrasn0w, and reboot!
4. Now your iPhone should be unlocked.

How to listen Tamil radios on your iPhone

So far I found, FStream is the one of the best iPhone app to listen our custom favourite radio stations. Also it is a free app that you can download from AppStore using your Apple ID. So please download it before proceeding next step.

Add custom radio stations in FStream
1. Connect your iPhone to any local WiFi network.
2. Open Fstream app on your iPhone.
3. Tap on More, under Web click Web Management.
4. Turn on Server Activation.
5. Browse the web address shown in the web management on your PC or Laptop which is connected to same router/network. Enter the user name and password. Default user name and password are admin.
6. Click Manage Your Website.
7. Input the following on each line then click "+" to add your radio stations link.












I have attached here the following radio stations' links.
CMR, CTR, MTR, TTR, GTR, CTBC, IBC, ATBC, 680AM(CANADA)

Note: You can add any radio link right from your iPhone. But I prefer this method to add it quickly and more customs like tamil fonts in the name.

How to view Tamil websites on your iPhone/iPod Touch

Note: You must have jail broken iPhone to follow these steps.

Before you proceed for following, please make sure you have installed OpenSSH.
If not, intall it from Cydia. Use WinSCP to connect your iPhone. If you are not sure hwo to SSH to iPhone, visit HERE. Someone has nicely guided.

Install fonts on iPhone
1. Connect to your iPhone using WinSCP via it’s IP address and use username: root, password: alpine
2. Navigate to this folder /System/Library/Fonts/ and overwrite the CGFontCache.plist with the modified CGFontCache.plist file (download here).
3. Now navigate /System/Library/Fonts/Cache and create a new folder MyFonts in the Cache folder. We’ll copy our new fonts in this folder so that they are easily identifiable and properly organized.
4. Copy all four Tamil fonts file (download here) to the MyFonts folder.
5. Restart/respring to and browse http://www.tamilnaatham.com/ to see the installed fonts work properly.
