Have you tried out Skype for iPhone that was released in early Apr? Skype for iPhone is a great application that lets you make free voice calls internationally over Skype. But there is a limitation. Due to certain reason, Skype restricts you to make calls over Wifi network only. By default, you can’t use Skype over 3G or EDGE network.
So, is there any way to break this rule and use Skype over 3G/EDGE?
The answer is YES if you’re using a jailbroken iPhone. Simply fire up Cydia and search for these two applications:
- Mobile Substrate
- VoIPover3G


By installing these two packages, your iPhone will fake Skype to make call over 3G and even EDGE network (see the “E” in the below pic). From now on, you can make free calls anywhere with your friend on Skype. Cool, right?

For those who are still considering jailbreaking, this is another reason why you need to jailbreak. To check out the details about jailbreak, you can read more about “Why jailbreak? Top 5 Reason to jailbreak iPhone”.

hi,
have you tried this simon does it really work with the new Skype app that was released?
Does installing voipover3G makes other apps unstable?
@Anup, base on my test so far, it works and is quite stable. You can also give it a shot. If you find any issue, you may just uninstall the voipover3G package.
This works flawlessly. thanks.
Infac after installing all my apps that requires wifi because i am using a different carrier on my phone works now. e.g. app store and itunes (on the phone)
Does it work with iPhone 3GS?
@Azbook, I haven’t tried it out yet. But I think with the latest version of MobileSubstrate, it probably works on iPhone 3GS.
the Viop3G is crashing your App store and Itune store.
