I've successfully managed to access the internet using Opera via a Bluetooth dongle in a PC whilst the Sony software was running (and connected) however I've had no such luck with my networked Bluetooth access point.
Other PDAs such as iPAQ, Pocket PC & Palm all work fine.
The phone can see & connect to the access point & 'seems' paired correctly
however I believe the problem is that Opera can't or doesn't see the connection.
There also is no option under Internet Accounts for a Bluetooth Account.
Aside from 'allow to connect without confirmation' there doesn't seem to be any other options or services for other bluetooth devices.
Via the PC I can see what Bluetooth services & options the phone has, but unlike most PDAs this isn't possible via the phone itself (very strange).
The lack of Bluetooth options & configurations on a phone that comes from the actual inventor of Bluetooth is astounding.
Has anyone managed to connect to a Bluetooth access point (not PC & dongle)?
