An interesting stat from mobile advertising 'enabler' AdMob: the conversation rate for ad-funded free apps on the iPhone is 10 times that of the full price versions. By conversion I assume they mean actual download and install onto the handset.

there's quite a bit of information out there at the moment that's showing consumer interest in ad-funded, both in mobile and on the web. (Outragous plug: I am loving the ad-funded version of music service Spotify). So could be we'll see plenty more companies making announcements in this space.

Factoid for a Tuesday morning: according to Mobile Entertainment magazine, more than 10,000 applications have been made available for download in the 5 months the app store has been live. 

So it's not in any danger of losing its no.1 spot, but it looks like Nokia has got a serious rival in the shape of the iPhone. Not only has Nokia joined the rush to find an 'iPhone killer' touchscreen handset, but it's also finding that its grip on the Smartphone segment is starting to loosen. Why? Well, Nokia recently said it had sold 15 million N95 handsets in two years; newbie Apple sold 6.9m iPhones in just Q3.

Of course, Nokia has the cushion of a range of other devices, but the N95 has been seen as a stellar performer. Could this mean we might see fewer devices but more quality from Nokia next year?
