Had to send my 7100g back and got a 7100r (on my carrier instead). Besides the case and key pad, are there any specification differences?

thanks.

All of the 7100s (internally) are the same. You can use the same applications, handheld OS, etc. The differences, as you noted, are just the keypad and case. Internally I believe they are 100% the same.

Ok thanks NJ. I like the case for the G better than R but as you know my G was unusually unlockable.

is it possible to buy a 7100g or 7100x case/housing and put your 7100r in it?

or is the form factor too different?

could be interesting but you would need to get the keyboard that works with a the different housings as well.
