How to unrestrict you iPhone 3GS to make Voip calls over the 3g network!!!
First of all, you'll need an iPhone 3GS (of course). This trick works for the version 3.1.2 of Apple's firmware. First, you'll need to jailbreak your iPhone 3GS. For that, you'll need to download the blackra1n.exe application from this website: www.blackra1n.com, then you'll need to run the application (nothing complex, just a one-button-easy-process) and wait for your iPhone to reboot (note that after this you won't be able to shutdown your iPhone again, as this is a tethered jailbreak, if you do, it'll restart in restore mode and you'll need to manually boot it again with the blackra1n program). When the jailbreak is done, you'll see a black-drop-shaped icon in the application list on your iPhone, tap it and install the cydia and Rock applications. When you finish installign those, tap the Rock application and then tap on "manage" at the right bottom of your screen. After that, tap "Manage Sources", then "Edit" (top-right of the screen), then "Add" (Top-left), then type exactly this: "http://sinfuliphonerepo.com" (without the quotes). Now, after confirmation, still in Manage>Sources, scroll down until you see a section called "User entered". Tap the arrow to show a list of applications. The first one should be an application called "3G Unrestrictor", install it. After installed, open the application from your springboard and select these application if you have them: Skype, Nibuzz, App Store (Choosing it also unlocks iTunes Store) and any other application that doesn't allow a certain type of connection over the 3G network system. And as a bonus, you might grab some other free applications for your iPhone, such as old game consoles emulators, file managers (iFile Cracked) and more!
