I have been looking for a tool to download my cell phone data... Not just my phone book but everything! While looking for tools that allow you to use your cell phone as a remote control, I found FMA. It's Windows based, it works on my Sony Ericsson T630 reasonably well (but only works on SE) and it's open source. So far, I haven't fscked up my contact lists.
Update: Since then, I've also learned about Device::Ericsson::AccessoryMenu and the Device::Gsm which can be used to automate your mobile phone communication.. Joy Joy!
