Question C9603 vs. C6902 + Customization Version

Two days ago I purchased the Z1 from a local retailer (Tel Aviv, Israel), not realizing that it was the C6902.
The problem is that its customization version is 1278-3595_R1A (software: 1272-6084_13.1.G.2.257.)

I hadn't realized that .257 cannot be rooted prior to updating to it because the OS prompted me to shortly after I first booted it up, so I was hoping to downgrade to .535, root, and update it to 4.3, and then install a custom ROM.

However, I gather from the thread with all the FTF collections (here) that no customization versions of 1278-3595_R1A exists. Does this meant that I can neither root nor install a custom OS?
(why I figured this is important: here.)

In conclusion, I assume that C9603 will get better and quicker dev support, so should I return my current C9602 and purchase the C9603 online (Ebay) while I still can?

Bonus question: why the hell does the C6902 even exists if it's just the C6903 without the LTE? Better to have it and not use it -- no?
(Note: LTE, or any form of 4G networks, including WiMix, is and will be unavailable here in Israel for the foreseeable future - at least to the general public.)

Thank you.

Just noticed that the title should be "C6903 vs. C6902 + Customization Version". I mistakenly misplaced the two digits in C6903.

Even ordering online has some problems. but any replacement to your phone is better!

That's what I'm unsure of - hence the pilgrimage for confirmation of my as of yet unverified findings thus far.

You can flash ANY C6902 firmware.

I thought that there is something wrong preventing you from flashing another firmware ftf on your phone.

Ah, then it seems I misunderstood where the different variations stand in terms of compatibility. I'll be installing the IN version soon and see how things go.

Thank you for the clarification.
