Now that the N80 IE is out and firmware runs on N80, the voip client makes that Truphone is just a simple SIP service as many others like Voipbuster,
VoipCheap.com, FreeCall.com, NetAppel.com, Poivy.com,
SIPDiscount.com, VoIPStunt.com, etc...
There is no reason that I would go with this service and prefer it to others as the sip setting they do are 100% similar to other provider,
Just a remark!
