ultrasnow not working...tried everything. PLEASE HELP
I have a 16gb 3g iphone w/ 3.0 firmware. I've jailbroken and installed ultrasnow via the gizmodo step by step guide (Jailbreak and Unlock iPhone 3.0 - jailbreak unlock iPhone 3.0 - Gizmodo)
Everything seems to work fine. But when I insert my meteor (irish sim). I got the "locked sim" notice.
Someone suggested I try reseting the network settings - didn't work
uninstalled and reinstalled ultrasnow - didn't work
restored to 3.0.1 firmware. then rejailbroke and installed ultrasnow - didn't work
Everything seems to work like the hundreds of guides I've read. The only thing that is different is that after I install ultrasnow, it asks me to reboot (not return to cydia). In the guides I've read, it just has return to cydia.
PLEASE HELP ME! thank you!
