Sorry wrong, I have unlocked Iphone from AT&T, you do the whole procedure with the SIM you intend to use. Only in SAM by carrier you have to put AT&T and to try several SIM IDs to get it working.if you iphone is lock to att...you will need a att sim card to start the first step with so you can get the IMSI, copy and past after you insert the sim carrier you want to used it for...and then connect it to itune.

It's not pointless at all. Unlock tickets are essential, they are like SHSH blobs. They allow SAM to trick iTunes into activating an unofficial SIM card. When Apple closes the hole, you will need the saved unlock tickets for any SIM that you want to be able to use the unlock with if you ever restore or update the phone. This isn't a permanent unlock, you must perform this process any time the firmware is restored, because of that it is key that you save your unlock tickets, otherwise when Apple closes the hole you will be SOL.
