unable to select which ipsw to restore to

[chill.]

I have an iphone 2g that was using 1.14 and unlocked and jailbroken using a t-mobile sim card. i recently downloaded and installed 3.0. however, now when i start my phone it asks for a valid sim card. i am also unable to restore my iphone and downgrade it, because it just uses the 3.0 ipsw by default without any prompt for me to select a different ipsw file.

how do i get to a 3.0 unlocked iphone from here? do i need to reinstall itunes to that a lower iphone ipsw can be used? do i need to get a valid sim card?

thanks in advance

Hold down the option key, and then click the restore button.

Hold down Option/Alt

I think it's Option or Alt that you hold down when you click Restore to select a specific firmware file. Might be Shift, but I'm digging up memory from over a year ago. It will give you a standard Open File dialog so you can select the ipsw file you want.

Its alt

thank you guys for the quick replies, option/alt is the same button for me and it worked perfectly.

i must have read over the restore guide like 2-3 times and always skipped over how to do it properly
