I have an OTB 1.1.2 and I recently bought an UltraSim from www.unlcokcellular.com I live in Jamaica and am on the Digicel network. I cut my sim and did what I should have done, put the combo in my iPhone expecting it to work - NOTHING!! What a disappointment!! Is it because I had downgraded the phone and jailbroke it but didn't install OKTOPREP, upgrade back to 1.1.2 and jailbreak again before installing the UltraSim?? HELP!! Why doesn't the UltraSim work??!!

I followed these Mac/PC instructions (README.txt included in the zip file) from the Dev Teams site when I installed a StealthSIM... Although you have a UltraSIM I presume the chips on the card are basically the same as the chips on StealthSIMS.
One thing not in the instructions that I did after I got the sim working was to install iWorld (found within "Tweaks (1.1.2)" in the installer.app) before I could make any calls.
Hope this helps and good luck.

Could let me know how it goes as I'm looking for a cheap SIM unlock for my other 3 phones...cheers
