HOW TO – Write iSync Phone Plugins
Great article on making iSync phone plugins from The Tao of Mac “Given that there seems to be a lot of misconceptions about exactly how iSync detects and understands the capabilities of mobile phones and pretty much no written documentation about the whole process, I thought it was about time I published my notes on the matter.” Brian reminded me that you can use’screen’ to talk to serial ports (for example, ‘screen /dev/tty.Bluetooth-Modem’), so you don’t need ZTerm to do this…Link.

The Projects link will take you to project descriptions and give you access to any Nokia developed downloadable code with an Open Source license.” They’ve got an NNTP news reader up there (source is on Sourceforge), and a few more things (Python, a SIP user agent library, and more). A web browser is coming soon (based on Apple’s Webkit). Also, “Series 60” has been rebranded as “S60”. Thanks Brian!
