I bought one yesterday, here in Western Australia.
Been using it for several hours now total and so far have NOT been able to find any menu items for wi-fi tethering.
This post is coming using USB Tethering which worked right out of the box. Tethered to an Asus EEE 701 Netbook running Ubuntu Linux 10.04.
So, if I can't find wi-fi tethering menu item, I'll need to get root access and install barnacle again.
Compared to my Sony Ericsson X8, that I've had since late last year, it's blindingly fast! The big screen is nice too!
So yes, I'm all in favour of a dedicated forum ... I reckon that the Ideos X5 is going to be a big seller, at least here in Australia where I paid $349 for an unlocked, unbranded (vanilla rom) with version 2.2.1 rom.
