I am using iPhone 3G running 3.0 Jailbroken and recently unlocked.

stupid questions:
1. If you unlock using Ultrasn0w, can you still use the original sim card from the contracted carrier?
2. Does anyone experience signal problems and "no sim card" problems? I am in Indonesia, and the carrier is Telkomsel.

The reason i unlocked it is because if i travel to another country, the roaming charges are very high. But when i am in Indonesia, i will be using Telkomsel Sim card that came along with the iPhone.

I also experience a slow-down in my iphone 3G. Does anyone else experience the same thing?

Thanks in advance.
