Differences between Omnia i900 / i908 / i908E

[Guest pixelatedscraps]

Hi all, I've been studiously reading up these forums for the last 72 hrs before I upgrade my T700 to an Omnia and I have just one question:

I'm living in Hong Kong right now, which means I have three variations of Omnia available to buy. These are the i900 / i908 and i908E. Can someone tell me what (if any) differences there are between the three, or are they just regional variations?

I can't seem to find any concrete information regarding this topic anywhere.

Thanks!
