setprop/getprop
<p>hi I am trying to modify values of some android properties. I am fairly new to this so I would appreciate it if anyone could help me.</p>

<p>i am trying to modify the following settings
ril.MSL and other data settings for my phone.</p>

<p>question is getprop shows me the value of net.cdma.rtsp.proxy.addr 
but does not for ril.MSL. </p>

<p>it does allow me to use setprop on both these attributes but it seems like it does not let me change the values.</p>

<p>is there way i can tell which properties are read only and which can be modified? furthermore, without root access can i somehow read the ril.MSL? its hidden from me at the moment. If the property is read only why cant I read it? </p>

<p>also are there any xml files i can use to edit/set to get this info?</p>

<p>thanks</p>
