JB, unlock, baseband, confused..help
When I bought my iphone 3G in Singapore last year,it came unlocked out of the box.
I am contemplating JB my phone but after reading threads after threads, I become more confused.
Since I am Windows user, I should use blackra1n to JB my phone. I currently have iTunes 9 and 3.1.2 firmware on the phone.
I know JB using blackra1n is fast and easy but somewhere I read about the baseband. Does that mean, if I JB my phone using blackra1n, I have to figure out another way to unlock my phone afterwards, which allows me to use different carriers' SIM cards since I travel often between Asia and America?
Is there a method that will let me JB my phone and retain my baseband?
thanks a bunch
