Saar: You seem to have studied the FICO scoring formula more than many of us. Does an "I" status on an installment loan mean it is unrated. I assume an "I1" status means installment loan and never late. There is a debate over this on another thread.
Not Saar, but normally if it is an installment account that is approved not used/or to new to rate it appears as an "I0", just a plain "I" I have never seen in the status area. I have only seen the single "I" listed as whose account. And yes "I1" means paid as agreed installemnt account.
The just "I" accounts show up on student loans. They don't want to rate for normally 12 months of payments, course, you'll get it if you're late.
