Iphone Softbank no network after JB and Unlock


iPhone Jailbreak and Unlock: The iPhone is working in Japan on the SoftBank 3G Network

I followed the basic steps posted everywhere on the internet to jailbreak then opted to use Cydia to install the yellowsn0w package for unlocking. After which I tried multiple times trying to get the SoftBank SIM to work. I tried switching Airplane Mode on and off, turning 3G off, restarting the phone and reinstalling the SIM. Nothing seemed to work. It would search for a carrier and then either give a SIM error or say No Service. I gave up for a couple weeks. Over that period of time I’ve toyed around with the iPhone getting my basic use out it if, connecting it to wireless networks and using it to attempt to communicate with the Japanese people. During that time I’ve restarted the phone a few times and turned Airplane mode on and off a few times and have done a couple syncs.

is this true who tried this if you do not have how to do?
+++++++================================
This was so helpful! I had the same problem with “no service” after installing my softbank SIM card taken from my old phone to my new unlocked iPhone. Once I read that you had to turn on 3G (I didn’t even realize it was disabled), I tried that and it worked! Saved me so much agony. Thanks so much again!
