if you are using 4.2 on your 7130 then send a message to the theme maker that designed the 8100 themes and ask them to export it under 7100. It is do-able..I've done it.

The 7100 series MUST be using 4.2 as the OS for it to work. And yes, the ONLY model is the 7130 that can use the 4.2 OS. The 7100 and 7105 cannot be upgraded to the 4.2

Same goes for the 8700 series that has 4.2. Curve Themes can be exported under the 8700 OS for 4.2.
