Where to get com.android.calendar for Android 4.0.3 from? I accidentally deleted the package com.android.calendar. 

Now it refuses to sync my Google Calendar. 

Where can I get this specific package to install it back to /system using Link2SD?

Model specifications:

HUAWEI U8666E
4.0.3
Baseband version: 2030
Kernel version: 3.0.8-perf-00271-g4fdddbe
Build number: U8666E-1V100R001C40B935
Russians over at 4PDA have a thread dedicated to the phone, which hosts a number of firmwares, including stock-based ones. Here is the Calendar app extracted from the &quot;Stock+&quot; one, uploaded to my AndroidFileHost for your convenience. You can also get other files from the package in case you need them.
As validation, the version number of the ROM as extracted from build.prop:

ro.build.version.incremental=C40B935
ro.build.tags=release-keys
ro.build.description=U8666E-user 4.0.3 GRJ90 C40B935 release-keys
ro.build.fingerprint=Huawei/U8666E/hwu8666e:4.0.3/HuaweiU8666E/C40B935:user/ota-rel-keys,release-keys
ro.confg.hw_appsbootversion=U8666E-1V100R001C40B935_APPSBOOT
ro.confg.hw_appversion=U8666E-1V100R001C40B935_KERNEL
ro.confg.hw_appfsversion=U8666E-1V100R001C40B935_SYSIMG

&quot;B935&quot; - matches your current ROM exactly.
