Unlock with Ultrasn0w questions
I am using iPhone 3G running 3.0 Jailbroken and recently unlocked.
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.
