com android phone crash 手机已停止运行

刷的cm10 不知为何突然狂报手机停止运行,crash 的原因是apn的问题，系统不知为何找不到apn的配置
my nexus s continue poping up com.android.phone crashing,but wifi and usb debug working well. finally found the reason is system can not find apn records.

solution:
1. install “APN Backup Restore.apk”
2. put the following apn file into the app's install directory,run the apk restore.
the attachments contains apk and xml file you will need.

if this not work,the only way you can do is just to swipe your phone's user data and reset the CM factory settings.
