Here's an entry on the blog of VoIP company Rebtel that looks very familiar to me. That may be because most of it is cut'n'pasted from our own story on the disabling of the Nokia N95's VoIP capabilities by some operators. Dear Rebtel: next time you might want to write your own words, or at least credit the authors of those you take - especially when you're trying to take the moral high ground (as in this case).
And, while I'm on the subject of our original piece, I'd like to call out Vodafone for saying: "There is a misleading perception that VoIP services are 'free'. This is however not the case when it comes to using VOIP over mobile where customers will need to use data connectivity to establish a service and may incur further charges. Vodafone feels responsible that customers should not incur unnecessary charges when competitive mobile rates are a cost-effective choice for customers."
As you know perfectly well, Vodafone, services like Truphone (the main company to complain) tend to operate over Wi-Fi rather than 3G/HSDPA. So, true, it's not usually free to do that - but I suspect the main problem for you is that you wouldn't be getting the revenue (especially in a situation where the customer would otherwise be roaming), rather than you being concerned about customers incurring high data costs. So, if you will excuse the pun, your statement does not ring true.
OK, rants over. Time for lunch...
