Flashing another region's ROM

[Replay]

Hi,
I have my Desire phone for four days now and it is a love/hate relationship so far

I live in Oman/ middle east and the desire is not yet launched for this region, so I got mine on ebay from a UK seller. it was unlocked but branded (Orange).
I found out that Desire does not support Arabic other HTC models do.

The desire will launch in this region very soon so I thought I will flash my phone with the ME rom when it is available. right? wrong!!
The official support guy from HTC told me that my phone should have a S/N for UK region and it will not accept a rom from other regions!

Is this true? Anyone tried a rom from other regions and it worked for him?
Please lie to me

Dear all,

I have excatly the same question as I am going to buy HTC Desire from USA and operate it in Egypt. I would like to request from HTC to the Middle east ROM that supports arabic to use it in my phone.

Is this possible either by straight or cracking way?

Regards,
Bassem
