I spoke to an account specialist a couple of weeks ago and he encouraged me to apply for a new card, as I’ve had my secured card for more than a year now and my score has gone up more than 100 points. He said I could have the two cards if I wanted to, or close one and keep the new one, but that they couldn’t unsecure. I said I didn’t want two credit cards with the same bank and didn’t apply. I still don’t understand how the upgraded account will reflect that back payment history, but sounds like something I would definitely try to do. I just don’t want to be the first one to try! lol.
