As we’ve covered already, Skype calls and instant messaging is not available for Fring users anymore. Fring calls it a cowardly act by Skype. Skype on the other hand says that they have not blocked out Fring without any reason. According to Skype, Fring was using Skype API in a way it is not supposed to be use, hence violating the API use agreement. This is what official Skype blog says about it:
However, over time, Fring’s mis-use of our software was increasingly damaging our brand and reputation with our customers. On Friday, for example, Fring withdrew support for video calls over Skype on iOS 4 without warning, again damaging our brand and disappointing our customers, who have high expectations of the Skype experience.
Whatever is cooking between Fring and Skype, its turning out to be a nightmare for a lot of Fring users. Some believe its a move by Skype because they are now coming up with their own Skype client on many mobile platforms, so they are trying to keep Fring’s competition at bay. Whatever is the case, all those users are suffering real bad who have been using them on mobile phones which do not support the native Skype clients and they are left without the capability of making or receiving skype calls on their phones.
