New ver 21 firmware has made this N86 a real beauty. Everything works fine and superfast. No bugs till date. Pity that we had to wait for whole 6 months for this firmware to release. The phone works very fast even with theme effects on. There is one more firmware due in the end of this quarter, maybe at march end or april first week or so. It will add some new features like multiple face detection and focus which is not being done in any phone till date and also much lesser jpeg compression so that images turn out bigger in size and details are retained much better. Dont know what other features nokia is planning to add. With ver 21 this is the best nokia phone till date
Also the new ovi maps 3.3 works fine on it. You just have to install the file for E52 or E72.
The voice navigation is really cool indeed and its totally free..
