Now for more stupidity. I got the card yesterday, signed it and immediately went out for lunch with the gf. Worked perfectly. I took it out to admire this morning and I noticed that I had signed the magnetic strip and not the place where its supposed to go and it won't come off.
My score was 686, it went down from last month because I let a few cards report and my util went down.
The Blue cards have a slightly different design and don't require a signature on the back of the card. If you turn the card around you'll notice it won't say "authorized signature" anywhere.
Congrats on the approval!!
