To mitigate the risk in this, the MD5 sum for the PS3 Update file can be checked. To do this in Windows XP, download MD5 Sum checker (md5sum.exe) from here. Then look at the URL of the update file:
http://dsa01.ps3.update.playstation.net/update/ps3/image/sa/2008_0415_dd2e675fce5d2eb28ca93bc32edb3de6/PS3UPDAT.PUP
The last part of the URL, from the final _ to the last / (in red) is the MD5 sum.
In this case (for 2.30) the MD5 sum is : dd2e675fce5d2eb28ca93bc32edb3de6
Now place the md5sum.exe in the same folder as your PS3UPDAT.PUP. Open a command prompt, cd to the update folder.
Then run:
md5sum.exe PS3UPDAT.PUPIf the output is same as the code you found as above, you are all set! You should get something like:
dd2e675fce5d2eb28ca93bc32edb3de6 *PS3UPDAT.PUPElse, re download...

Completely off-topic but I just subscribed to your feed. FYI.
Cool! I am just back from China and will put up some stuff about my trip soon :)
Don't you think Sony already does a checksum after downloading? I would certainly hope so!
Read the first line: "If you are like me and living in a low bandwidth country, you will face the issue of having to download the PS3 Update file using a PC and then updating via the USB method."
Sony has no way of performing a check in this case. Also, even in other areas, you are strongly recommended to install the update via USB as I have read on forums cases of issues occurring if the update is not downloaded in one go.
