While I have not tested Fring yet, I have no suitable WiFi phone but it should not last, I already love Fring !!!
Having a one-stop solution to my mobile phone, my landline-over-ADSL-with-low-rates-phone, my Skype phone nightmare is more than a dream.
In a couple of words, Fring is a piece of software designed to run on your mobile phone and that routes the transmission to the media available: standard mobile, mobile data (3G), WiFi and so on with regards to the dialed number in order to optimize the cost of the communication. Fring also support various IP based solutions such as Skype, MSN Messenger, ICQ, Google Talk and SIP. For sure mobile phone operators won’t like that. Running on one single device means that all my contacts’ information does not need to be replicated on various devices, what a relief!
It seems to like Symbian OS as numerous Nokia phones appear to be supported by now. Windows Mobile based devices is also an option but it crashed on my HP IPAQ nx2495… No doubt an iPhone version of Fring will come with time.
No business model is claimed by now. Advertising based operation or big player buyout?
