Ok, so I have a trial N900 from WOMWorld, and I've been trying to hack it to do cool things. So far I've done this:

And written up a how-to here:

As I say in the article:

"I’ve only got this N900 as a trial for a month. I’ve no incentive to develop this further as I’ll have it give the device back :-( . It’s a proof of concept. I’ll hand this over to the Maemo community to develop further. I’d like to see this as an app that can be installed from the repository, with a nice GUI to configure the various options. Other features that would be good to add would be:

• Choose what networks to sync on, or what type of network.
• Maybe sync over 3G only if there aren’t many new pics since last sync etc. Limit data.
• Option to sync when the camera shutter is closed.
• Software to configure the OSX side.
• More testing! What happens on failed syncs etc.
• GUI

If anyone does take this on and extend the idea, please credit my blog, or me by name – Iain Wallace."

So, if this is of interest to anyone, try it out. Let me know if you spot any mistakes in the post or it needs more info. And if anyone's interested in developing this idea further, well, feel free! Though I'd appreciate being kept up to date.
