Dual-SIM Phones?

[55Kevy]

I realize that this may not be the optimum forum for this question, but here goes anyway: Are there any PPC Phones out there that accept 2 SIM cards, or is there a way for a single SIM to have phone numbers from 2 providers? I have a business phone and a personal phone and it would be great to be able to combine them. As a further complication, the business provider is Indonesian and the personal provider is US.

Any help?

thanks!
