    First of all I recommend doing a full nandroid backup using the ROM manager.
    Start the phone in recovery mode and do these steps:

    1) Format cache
    2) Advanced> Format Dalvik Cache
    3) Install the deoxed version of the new ROM
    4) Reboot phone and allow it to load fully
    5) Restart and run step 1 and 2.
    6) Install the language pack
    7) Restart phone.

    I have been doing this for every ROM update and I have had no issues. It keeps everything including your data as you left it.

    BTW guys i have another question regarding this issue. if i flash new version as you told me, should i flash packages like CM7_Hboot_MIUI_MOD or RTL-Persian again? cause i'm using CM7 hboot and im a persian user and currently i have flashed these packages.

    The Hboot thing no, that only needs to be done once to get you a more "decent" boot loader.

    No idea how the RTL-Persian mod works so I can't tell you anything about that one.
