Oh we understand the question and also that you dont want to pay 😀
So to answer your question no, there is no free alternative that would accomplish the same as 3Gunrestrictor.
Voipover3G is free but has the following limitations
◦It is configured to only trick Fring and Skype in the default configuration.
◦You cannot add new apps easily - You have to edit config files, which is too complicated for most users.
◦It doesnt work with the AppStore and iTunes Store - You wont be able to download applications and podcasts bigger than 10MB.
◦It doesnt work with YouTube, you wont be able to watch videos in the same high quality as on WiFi
3G unrestrictors features:
◦An easy to use configuration app - Add whatever apps you want and unrestrict them from their chains!
◦Works with the AppStore and iTunes Store
◦Works with YouTube and lets you watch movies in high quality
Applications verified to work:
◦Skype
◦Slingplayer
◦YouTube
◦AppStore
◦iTunes Store
◦Nimbuzz
◦Fring
◦Truphone
◦FriendCaller
◦SipPhone
Applications verified not to work:
◦MLB At Bat 2009
I tried getting this to work, but it uses Apple's new streaming technology that checks how much badwidth is available and then chooses the stream. I didnt find a way to change that behaviour. A later version of 3G Unrestrictor might make it possible. I might find a solution sometime later.
◦BBC iPlayer
I tried to get it to work too, but it seems that the iPlayer uses a system that detects whether an IP-Address belongs to a mobile internet provider and then blocks it if the mobile, iPhone version of the iPlayer is used. This is possible, because the iPlayer uses the service of a company at which every internet provider has to register it's IP-Ranges. Since the check whether a mobile internet connection is used is made on the iPlayer side and not on the iPhone's side in the Safari app, I cannot unrestrict that.
Answered your question in detail or what?🙂
