I am using latest Yonip  2.32 kernel (#53) with CynogenMod 8.4 (Froyo 2.2) and I have a problem on 3g usage. When I use more  continious 3g data, my phone randomly freezes and then reboots. I wrote discussion thread about this issue but I cant find any help. About solution, I believed that, by 3g configuration, this problem can be fixed.  I used 3g/edge speed improvement  script and I have configured some parameters to limit hspda speed. By default my phone have 3.6 mbps hspda speed and if I change this limit to 1.8 mbps it prevents freezing. By the way I prepared a update script and can be apply by manually editing /system/build.prop file. After editing this file, don't forget to back up build.prop file as build.prop.bak. You can find the parameters and update script file below.
