<p><span>This</span> <a href="GUID-E0ED671A-BBDA-4C07-828F-BD35782D9B36.html#GUID-E0ED671A-BBDA-4C07-828F-BD35782D9B36">SystemInfo Service</a> API
is supported since <a href="GUID-1A3ECAC1-3F09-4602-A1CD-82164040A664.html#GUID-1A3ECAC1-3F09-4602-A1CD-82164040A664">WRT 1.1</a>.</p>
<p>The SystemInfo Service API allows <span>widgets</span> to
access and modify system information on a device. The API is integrated into <span>WRT</span> through
the <a href="GUID-571AF37F-1E95-462A-92D2-FEA2E62F1559.html#GUID-571AF37F-1E95-462A-92D2-FEA2E62F1559"><code>device</code></a> object.</p>
<p>For an overview of the service and the API, see section <a href="GUID-E0ED671A-BBDA-4C07-828F-BD35782D9B36.html#GUID-E0ED671A-BBDA-4C07-828F-BD35782D9B36">Accessing and modifying system information</a>.</p>
<div><h3>Using the SystemInfo Service API</h3>
<p>To use the SystemInfo Service API, your <span>widget</span> must
first create <span>a service object for it
using the <a href="GUID-04095E9A-50E7-4E5F-BD6F-71DA281A0080.html#GUID-04095E9A-50E7-4E5F-BD6F-71DA281A0080"><code>device.getServiceObject()</code></a> method</span>.
Use <code>Service.SysInfo</code> to identify the service provider
and <code>ISysInfo</code> to identify the supported interface:</p>

<pre class="codeblock" id="GUID-9F7EE91E-7245-44A9-BFAE-BF043CA4E67D-GENIDd0e67882">var so = device.getServiceObject("Service.SysInfo", "ISysInfo");</pre>
<p>This service object can then be used to access the services provided
by the API:</p>
<ul>
<li><p><a href="GUID-279A3698-D09B-44BF-8340-739E19F94727.html#GUID-279A3698-D09B-44BF-8340-739E19F94727"><code>ISysInfo.GetInfo()</code></a></p>

<div><h3>Emulator support</h3>
<p>The S60 5th Edition SDK emulator provides partial support for system
