I'm a late upgrader with a problem
I created a custom ipsw and upgraded my iphone 3G to 3.1.2
the Baseband wasn't upgraded and is 2.28.00
can the phone be unlocked with ultrasn0w ? is it safe ?
can i upgrade my modem to 4.26 ? should i want to ? any new features?
I'm seeing some slowness in my apps after upgrading to 3.1.2. is that common ?
