Restrictions from Apple Apple tightly controls what software can be installed on iOSdevice: only approved apps offered through the App Store areallowed. Theres a whole universe of apps available through other means.These apps arent available at the App Store due to Applerejecting them for various reasons (violating terms of service,competing with Apples own apps, sometimes poor code orsecurity problems, etc.).
Unlocking vs Jail breaking The basic difference is that jailbreaking is about controlling whatsoftware you can install on your iPhone (or other iOS device),while unlocking allows you to choose what mobile phone carrierthe device will work with. Jailbreaking can be accomplished using various tools including JailbreakMe.com,Redsn0w, Evasi0n, Limera1n etc. allows you to remove Apples restrictions on what software you caninstall on your iPhone, thus allowing you access not only to the AppStore, but all the other compatible apps as well (many of these canbe purchased via Cydia, the leading alternative app store).
Unlocking vs Jail breaking Unlocking Apple controls the iPhone (and 3G version of the iPad) is bylimiting the phone carriers that it works with. In the U.S., forinstance, the iPhone is only officially sold and supported on AT&T. It allows you to change the carrier that the phone works on. This requires that the iPhone is compatible with your carrier ofchoice and that youve got service on that carrier
Types of Jailbreak A tethered jailbreak requires the iOS device to be plugged into acomputer when turned on. If the iPhone is not plugged into acomputer and booted with special software the device will notenter a jailbroken state. Video : http://www.youtube.com/watch?v=QlYHV0vmTRU Untethered jailbreaks do not require a computer. Everythingrequired to enter the jailbroken state is contained on the iPhone.Rebooting away from a computer does not affect the jailbreak.iOS 4.3.3 and older jailbreaks including PwnageTool, limera1n,greenpois0n and sn0wbreeze are untethered solutions.
Introduction to Cydia Launching Cydia for the very first time Cydia is very easy to use and manage. If you know how to use AppStore, you’ll have no difficulties with Cydia. The first time you launchCydia, you’ll be asked to select the type of filter:1. User (Graphical Only)2. Hacker (+Command Line)3. Developer (No filter)For normal users, you can just set the filter to “User”. With this setting,Cydia will filter out those applications in which you’re not interested.
Cydia – At a Glance Home – The home screen shows the latest news from Cydia.You’ll also find featured packages, source information, userguides and other developer-related information here. Sections – You can find all the available applications anddownload them here. Application packages are organized intospecific categories. Changes – “Changes” shows you the latest releases availableand also alerts you for any application upgrades. Manage – Keep track with all your installed packages. You canuse “Manage” to upgrade / uninstall packages. Also, its theplace to add/remove Cydia source (will cover more later on).Search – Search for applications in Cydia

Switching betweenUser/Developer/hacker When you launch Cydia for the first time, immediately afterjailbreaking your iOS device, you probably remember seeing ascreen, which prompts you to select if you’re a User, Hacker orDeveloper. Normally, you select User and forget about it. But if you’rewondering how to switch to Hacker or Developer, there is an easyway to switch. Tap on the Manage tab at the bottom. Then tap on the Settings button at the top left corner. You will again be greeted by the same screen. Tap on Hacker/Developer to switch to that mode.
Troubleshooting – Boot in Safe mode If your iPhone is constantly crashing or you think a certain tweak iscausing something in iOS to act up, reboot your device by holdingthe Home and power buttons simultaneously until you see the Applelogo. Once the logo appears, hold down the volume button like theinstructions say and you’ll enter into Safe Mode. This means that all of your jailbreak tweaks and extensions are turnedoff, making it easy for you to go into Cydia and remove thepackages that are causing the problem. If you’re not sure what tweak is responsible, then you’ll have to tryuninstalling and rebooting until you notice the problem go away. It’snot a foolproof way to troubleshoot, but it’s not bad for a free, built-insolution.
