របៀប Update iPod touch ឬ Jailbreak iPod touch Verson 2.2.1 to 3.1.2 or 3.1.3 for free
វិធីននេះថាងាយក៏បានថាពិបាកក៏បាន អាស្រ័យលើលោកអ្នកប៊ិុនប្រសព
ជាដំបូង លោកអ្នកត្រូវមានះ
១- កុំព្យូទ័រ Window or Mac Os
២- ត្រូវមាន iTunes 9 or Higher version ក្នុងកំុព្យូទ័ររបស់លោកអ្នក
(I just recommend you to use Mozilla Firefox for your computer and if you use Internet Explorer, it sometimes won't work.)
៣- ត្រូវទាញយកកម្មវិធី២ ពីអិនធឺណែត តាមរយះវិបសាយ :
    1- Click on: Firmware
scroll down and click to find version you like ( for example I choose ipod touch2G 3.1.2/7D11 for ipod touch) and then click on download.( better to save in your Destop).
2- Click on: Blackkra1n
If you use Window, click on Window and if you use Mac OS, click on Mac OS and then save in your Destop.
After you finished download, go to your itunes with your ipod touch plug in and then hold Shift and click on Restor and click on ipod2,1_3.1.2_7D11_Restor and click open.( Wait for a while until your ipod touch restore finished)
After it was finished, click on the other program called blackra1n and double cick on it to install to your ipod touch. It's done. Now your ipod touch update to 3.1.2 version.
Note: for me I use different way. After I restore my ipod touch and then I go to , Please read the instruction(
Spirit Jailbreak iPad, iPhone, and iPod touch) and then click on Download and save it in your destop( the program call Cydia and then you double click on Cydia and then see the instruction on this video how to install Khmer fonts into your ipod touch. and then you done ! It seems a little bit complicated with this thing but you try and let see how it works.It works very well with my ipod touch version 2.2.1. Enjoy ! if you have any question about that, just leave your comment on my blog. Thanks.

Note: if you update with the iTunes, it costs money and take too long to process it. If you follow my way, it take only 20 minutes.
