For those users that are planning to Jailbreak on iOS 4.2.1 then I highly recommend adding this Cydia Source into Cydia after you jailbreak so you don't have to manually input all the Cydia Sources manually. This will automatically add all the best Cydia Sources and give you access to all the best Cydia Tweaks, Themes and Apps for FREE with just a push of a button. Follow the steps below. 1. Open Cydia 2. Tap Sources 3. Tap Edit 4. Tap Add 5. Type this url in the box (cydiasource,n e t) without the spaces and switch coma for a dot in the url. 6. Tap "Add Source" 7. Install the package labelled "All Sources". This will give you all the best Cydia Sources to have access to all the best Tweaks, Apps and Themes for FREE.

I did all this and it worked perfectly on my iPhone 3g until it refused to show my sim network. The phone was originally locked to telstra then unlocked properly and I still have a telstra sim. But it only shows 1 bar with no data network like it normally does. I have it in a place where I would normally get 5 bar full reception and I still have only 1 bar. Removing and re-inserting sim does not work, it just shows "no sim". Anyone able to help??

On an iPhone 3G, Is it possible to upgrade to a higher firmware than 4.2.1 once you have gone to a baseband of 06.15.00?

Thank You so much! I've been wanting to jailbreak my iPhone 3G for a very pong time and I tried using other softwares but I couldn't. This helped a lot. Thanks

The "install ipad baseband" is nowhere to be seen

I did this and it all worked, but the phone is saying sim card failure, but the sim card works in another unlocked phone, any ideas what to try next?
