Problem is, the voice Skype client isn't officially supported on this phone yet - the CPU is allegedly not fast enough (! for a voice codec?!). I've got an SP5 - same phone - and even when the binary was hacked onto the phone, the lag was abysmal.

If you want to skype sensibly you need one of the higher up HTC devices (like the qtek 9000) with a 400MHz CPU and touchscreen interface - these *are* officially supported.

An unlocked phone and local pay as you go SIM is the cheapest way, really, but a heap of hassle!
