Jailbreak your iPhone

How to use Skype on iPhone Over 3G Network.


Skype is available in App Store most 3G networks should support Skype presence and chat.  However, Skype calling is not possible via the iPhone 3G Network you mest be logged on to WiFi Zone. Because Apple did not allow use Skype over the more prevalent 3G network, limiting itself to WiFi only even though 3G had the necessary throughput for it. Apple claimed this restriction was imposed simply because it was a carrier-dependent decision since transferring data over the 3G could be costly for carrier.So If you wants to use Skype, Fring or Truphone like apps over 3G, EDGE or GPRS you need to remove this restriction yourself, you need to first jailbreak your iPhone. Once that’s done, it’s a simple matter of installing from Cydia the “voipover3g” app. That’s it, simple as that. Note that this works for other VOIP programs as well, not just Skype. “voipover3g” app uses MobileSubstrate Library tricks apps into thinking that they are on WiFi even though they are on 3G/EDGE/GPRS. In the default settings you can use Fring, Truphone and Skype.

Have Something To Say ?

    Regarding the story above titled “How to use Skype on iPhone Over 3G Network.” where it tells you how to use Skype over edge or 3g and it tricks the phone into thinking its using wifi….I have a few questions:

    1) Will this work for free on only skype to skype and must I sign up for Skype Credit when calling from my unlocked iphone to a mobile number or landline?

    2) Will this incure data charges or minutes usage on my unlocked t-mobile 3G phone if I am in the US calling landlines or mobile #’s?

    3) The big question is will this incure data charges or minutes usage on my unlocked t-mobile 3G phone if I am in Europe and calling the US or say Australia? (I assume it will since I was told to turn my phone to Airplane mode when using skype via Wifi in Europe and to turn off Data Roaming also to avoid a fortune in added charges)

    4) Will this work if I turn off data roaming and go into airplaine mode while in Europe? (I assume it will not work but wanted to ask)

    5) Am I to assume this app is simply for the ability to use skype from edge or 3g and does not force me to use a wif connection?

    6)…and if I am going to call a mobile # I need to buy credit….

    7)and if I am going to the EU this will not work due to high roaming fees and I am better off using the wifi in EU and buying credit on skype to make calls to US and EU landlines and EU and US mobiles?

    Thanks and sorry for the repetative questions but I want to be sure and I am a newbie to iphone and skype mobile
    😉 Hey we were all grreen at one time!
