Actually, sorry to disappoint you bro but I have to drop this bad news on you. Having read through K-tai Watch website and several sources, it has been confirmed that the Wifi feature on the N906iL is simply restricted to FOMA service area in Japan only, just like how 1-seg TV works on NTT Docomo phones. Simply to put, unless a Docomo FOMA simcard is inserted into the handset, the Wifi feature will be locked down, as simple as that.
This move is actually understandable because with the new NEC N906iL model, NTT Docomo this time has introduced a new flat-rate Wireless LAN data plan known as Home-U, as revealed in this japanese article by K-tai Watch. It comes at a monthly flat-rate price of 1029yen, and you will be able to use data access at home on i-mode, W-LAN networks as well as making free voice-calls via VoIP feature at home, as long as you have the NEC N906iL handset with this Home-U plan subscribed. On top of this new plan, current domestic NTT Docomo subscribers must also have the packet data service (known as Pakehodai to them) or packet data-full (Pakehodai-Full) subscribed first before been able to use this service, on their NEC N906iL.
Their Pakehodai-Full plans are actually similiar to what we have here locally via service providers like Singtel or Starhub, where we pay a monthly flat-rate pricing for fixed data access plans via 3.5G networks, for example ST's Broadband on Mobile, and Starhub's MaxMobile plans.
As for the upcoming SH906iTV with added GSM network capability other than 3G, yes I have already highlighted this on my SH906iTV post previously on the 1st page over here,maybe u missed that post earlier on. This is certainly good news for exotic lovers, for those who are infatuated with Sharp's Cycloid-style hinge models and would like to try out the SH906iTV this time round, as previously most of us couldn't 'own' the SH905iTV due to it been 3G-network capable only
awwww~!
