I just installed iPhone OS 3.0 on my first generation iPhone using redsnOw. I’m quite pleased with the features of the OS 3.0. The most useful feature is the search feature and the copy and paste feature. The SMS app has also improved a lot, landscape mode is included. But unfortunately I couldn’t install any cracked apps as the mobile installation 2.2.1 patch which we used in 2.2.1 didn’t work here. But, I found an easier way to install cracked apps. Here’s how you do it:
Firstly, Go to ‘Cydia’.
Click on ‘Manage’ tab on the bottom.
Now click on ‘Sources’.
Click on ‘Edit’ and then on the left hand side click on ‘Add’. A box will pop up asking you to enter a url source as seen in the screenshot above. Type ‘http://cydia.hackulo.us’ (no quotes) and click on ‘Add Source’. It will take a few seconds as Cydia will update your sources.
Once it’s done, go to Sources> Hackulo.us> AppSync (the first one in the screenshot above) and install it. This is a small app which patches the mobileinstallation file.
Voila! You should be now able to install cracked apps on the iPhone OS 3.0. Connect your phone to your computer and install any cracked app in iTunes.
