Is it possible? I read that this was possible on former Series 60 phones, so i'm asking if it would be on this one.
Is there any hack out yet? Or is it even possible?

I've NEVER seen that mentioned for the 6220; I'm pretty sure it doesn't have the hardware inside... For wlan you'd have to look at the the N79.

Obviously this device has not Wi-Fi integrated hardware. It doesn't sense for Nokia to spend money for additional device. It shipping other similar symbian devices with integrated Wi-Fi.

So, forgot about this idea :)
