After update to OS3.0 JB and unlock, i cant import my sim contract..after loading a while when i go to contact is empty have try few times importing sim contact...anyone know why..

Thanks

If i'm using a US locked iphone 3G on 3.0.1, there is still noway to unlock right? if i upgrade to 3.1.2 by using windows, the only method is using pwanage?

For those who without a official unlock set iPhone 3G or having problem JB with blackra1n, or without a mac and want to upgrade to 3.1.2 and unlock, this is a custom ipsw i build with mac, already JB cydia added and will reserved baseband 4.26.08. Just install by itunes holding shift and click restore and select the ipsw. After everything is done, just install ultrasnow through cydia for locked set. This ipsw only for iPhone 3G, since the unlock method 3.1.2 for windows is no yet out

Jailbreak with blackra1n will it cause the whole phone back to factory default settings if the phone batter completely drain off? cause my ipod 2nd gen on 3.1.2 JB with blackra1n, but after the battery completely drain off, and when in plug the charger..whole ipod back to default sethings..everything wipe off..will iphone face this problem?
