>>>you want both SIM's to be active at the same time??

>Yeah- they call it "dual standby" meaning they're both active until one enters a call. If you look for "dual standby" on eBay there's heaps of options, though most have poor touchscreens and are using the Chinese Nucleus OS that allows some Java apps to run but none of the cool apps people want.

Interesting - but why not just forward one number to the other number? Then you just need one SIM card to begin with...
