So my n900's touchscreen has completely stopped working after a few weeks of working on and off, but before I send it away for repairs, I'd like to completely back it up since it will undoubtedly be wiped at Nokia/Optus.

However, as well as not having a working touchscreen, it also doesn't automatically connect to the internet when it's booted up, so all the SSH related solutions I've found are somewhat unhelpful in this situation...

If I can connect to a saved WiFi connection via terminal or keyboard shortcuts, I'm guessing I should be able to use SSH...

Does anyone know how I'd be able to back up everything? (Contacts, SMS, Applications and their settings, files, etc)

I'd also like to be able to export my contacts into something like an Excel spreadsheet so I can access certain numbers

I pretty much just want to be able to go back to the exact same phone when it comes back from repairs...

Thanks in advance!
