What is OpenMoko
Openmoko™ - Open. Mobile. Free.
Openmoko™ is a project dedicated to delivering mobile phones with an open source software stack. Openmoko was formerly

Hacking with the phone
Using HTML and Javascript to make the UI of the system
<html> <head>
<script> ….... </script>
</head></html>
Hacking with the phone

<html> <head>
<script> device.vibro(1000,70);
….... </script>
</head></html>
The system browser , its a very simple Webkit Browser, enriched with special javascript objects.Those objects are able to control the phone
GSM DEVICE
Call to Sysfs to make the phone vibrate
Hacking with the phone
Example application for scanning wifi networks
<ul id="list"> <li> Scanning for Wifi </li></ul><script>
function scanfornets(){var nets=device.shell_exec("iwlist eth0 scan | awk '/ESSID/ {print $1 $2 } ' ","");var p=nets.split('\n');for(var i=0;i<p.length;i++){ var v=p[i].split(":"); if(v[1]!=undefined){ icon('wifi_'+i,"Net : ",v[1],"list","systemjs/dstatus.html"); } }}
scanfornets();icon('back',"Back",'',"list","systemjs/dstatus.html"); </script>
