SuperCID after flashing ROM

---

Hello Guys,

i unlocked my CID and flashed my Wizard succesfull but now, I want to flash the old original ROM. I want to know, if the CID is now every time a SuperCID or must I unlock my CID again bevor flashing?

If the CID is still a SuperCID how can I Restore the backup of my original CID for warranty?

CID means carrier id, is that right? Therefor i would say that my colleague with the same Wizard from T-Mobile Germany has the same CID, is that aslo right?

I hope you can help me.

I am also wondering how we can restore the original CID lock...!?
