Hmmm, is there a chance to see an Symbian device with WIFI (wireless lan) in future? It doesn't need to be a phone, of course a P810 or BenQ with an (optional) wireless module would be my favourite.
Symbian device & wireless lan
Of course, there's always the chance to see that some day. There's nothing in the technologies (WLAN or Symbian) that prevents companies from doing it when they feel the time is right.
No Symbian licensee has made such announcements so far, though.
Mitsubushis concept phone had Wi-Fi (802.11b), I was thinking there could be some issues with Network Providers though, as it could in theory make voice over IP possible.
Can't remember when or where (though it could have been Reuters) but there was a report of a company looking at making a combined Smartphone\DECT phone. When away from your DECT base station it would function as a normal mobile. However, once in range, it would use either Bluetooth or Wi-Fi to connect to your base station and allow you to make calls over your landline. The article speculated that Wi-Fi would be the prefered option as it has a similar range to current DECT phones.
I've been expecting something like that for ages. It's a pain in the perverbial having to enter all your numbers in your mobile AND DECT phones.
I know this doesn't exactly asnswer your question, but it's (I think) interesting and relevant!
