Hello,

i got "invalid sim" and "sim card failure" message after unlocking my i-phone 4 using the ultrasnow.

i tried rebooting it several times, it doesnt help

i tried reseting network settings, it doesnt help

modem firmware : 4.10.01

i tried sim card in another phone, it works.

Thanks for your help

Thanks

04.10.01 is not supported by ultrasnow. You need to use stuff like Gevey in order to unlock your phone. Welcome to the forum.
 
Thank you !
i am a newbie for i-phone 4. can you guide me how to get the correct gevy sim and instructions to install it?
 
Unfortunately I can't help you to get any Gevey also can't help you to install it, you do it, and you do it at your own risks. Gevey is a sim card you can purchase from Amazon or bestbuy etc... Google to know more about it, I personally don't have any experience with Gevey.
