There are two online happenings I'd like to draw your attention to today. Firstly, the guys at AutoTrader - who released their Symbian application a week or so ago - are holding a one hour 'Twitter Takeover' at 12pm GMT on their AutoTrader UK account, so if you're looking for improvements to their app or have questions about mobile support then get involved by asking questions. Secondly, the folks at SPB (who make Mobile Shell and SPB TV, among others) are holding their annual web survey on your smartphone preferences and habits - here's the start page for All About Symbian readers - with some prizes for respondents, detailed below.

For people replying to the SPB survey, drawn at random from the entries, "the first place holder will be rewarded with a mobile device of their choice (within the limit of 1000 USD) from Amazon or eXpansys". Second place will be rewarded "with a 100 USD worth of smartphone accessories of choice". The prize for third place is "100 USD worth of our software".

So two ways to get involved, to make your voice heard and (maybe) to win something?
