I had a soft-upgraded 1.1.3 with geo ipsf unlock, and I decided to restore from itune to 1.1.3 and use Ziphone to jailbreak and activate to see if the phone is still unlocked.

After i did jailbreak and activate from ziphone, I installed BSD, ssh and run the last part of the script from geo ipsf which only copy the singal.app over.

It works. youtube, map, sounds are working without any fixes!

I was wondering if you were experiencing any signal issues.

I have an official upgraded 1.1.3, then upgraded the baseband to the 1.1.3, unlocked with anysim 1.3. I get dropped calls all the time. I did not get these until I updated the baseband.

I was thinking of switching unlocks and re-locking anysim and then proceeding with what you did. IPSF then restore.

What do you think? I do not want to go through the trouble if it is a general baseband problem.

I don't have the problem so far, but i noticed if you switched on/off the edge from service.app, you will get 1 bar singal which require to launch singal.app to restart the baseband.

Other than that, i don't have any drop calls and singal issues. Singal.app is great and handy when you need to restart your baseband. no need to power off and restart the phone.

Even anySIM unlocks are restore resistant. Its once you change your firmware (either erase it or upgrade to a newer version) that is when you test if its truly resistant.
