Hello
Just 2 ideas:
How cares about GSM WiFi handovers? I just want to make free VoIP calls.
About the ISPs blocking VoIP:
I believe they will not block VoIP because a lot of theire services are
VoIP based, like the webcasts, the TV shows over the Internet, and all
the multimedia stuff they want us to buy.
In Portugal I already did 3G VoIP calls from TMN and Vodafone.
I would really like to try this phone :)

Well it is incorrect to say that.
In places like USA or London, a lot of areas are covered by local wifi
providers, some are free, some aren't.
You then can use them to drop some of your local or international calls
cheaply by using wifi.
But the point is without operator cooperation, there's no seamless
handover between GSM and WiFi, and the operators don't want to lose the
revenue on the voice, so they are unlikely to support it.
BT have an arrangement with Vodafone for their Fusion service (using an
in-premise Bluetooth basestation and a phone with GSM/Bluetooth), but
they're big enough to force an operator's hand.
For general GSM/WiFi UMA, it's unlikely the (UK) operators will allow
other providers access to their networks, as it reduces their revenues.
They're already p*ssed off enough that they're being forced to reduce
roaming charges (currently on voice - but the EU is likely to look at
data charges which can be extremely costly).
They are desperate to keep revenues.
