Imate PDA2K rom update, Orange Partner Israel

[pandavi]

I have ordered a new Imate PDA2K from Australia through Ebay, haven't got it yet so I do not have all the data incl. all rom versions it is running under, however, Orange Partner, my Cell Phone provider has released a new Rom version on it's website, Orange_Israel_V1.72.187_Dated-3-2-2005.exe designated for the IMATE XDA II, (the same but without the sliding keyboard) which is the device they sell here in Israel, and which contains Hebrew language.
My question is, would it work on my new PDA2K?, what do I have to do in order to be able to reinstall the original rom in case the new one does not work, I have read the "Blue Angel for beginners" at wiki.xda-developers.com, however it is rather complicated, well at least for a new user.
Thank you.

I would not install the ROM for the XDA II, I really don't think the only change is the sliding keyboard. It's a different device and comes with dfferent hardware and I have a feeling that you are going to screw up your phone, especially since u are getting the phone from australia - what would u do if u screw it totally? U are stuck with a dead duck.
If I were U - I would not take the risk.

This is just my opinion.

Thank you for sharing your opinion, I thought so to, anyway there is a rom update at Club Imate, I think I will use that one.
From what I have read in the XDA@ forum, the update I was talking about in my question is the exRom, it appeares so in many devices in some posts.
Thanks again!
