With Skype's native Symbian incarnation still somewhat AWOL, it's interesting to see that Nimbuzz has stepped into the breach with their own pay-as-you-go VoIP to traditional number service, dubbed NimbuzzOut. More details and links below.

From the release:

"NimbuzzOut lets you make incredibly cheap international calls from your mobile, to landlines and mobiles anywhere in the world. It’s the first pay-as-you-go product that we’ve ever offered, and it will transform your mobile into the cheapest way to make international calls – who would have thunk it?!

From today, you can purchase NimbuzzOut credits direct from www.nimbuzzout.com or your Nimbuzz mobile app and save up to 95% on the cost of a traditional international mobile call!"

Comments welcome in terms of compatibility with different Symbian-powered smartphones, if you've got the time to try it. Here's the NimbuzzOut launch video:
