Works Just installed on old Samsung Galaxy S2 and tested using an existing peoplefone account. Seems to work. Unlike one review, there does seem to be a setting to disable the app if there is no Wifi (ie. do not use 3G) Was able to call and receive calls. I think you should not try to install this unless you have a Peoplefone account. It did take several minutes for the app to start to work properly.
Useful app For Peoplefone customers this is a nice app, that allows to being able using their system on the go. One major drawback though is, that it it not possible to disable calling over 3G. Definitely need control over that, as well as being able to control the background process - if you don't want to be using the app all the time.
