How does Rock know that you've had it previously installed?

Hi guys, I had Rock installed on my phone, but I did a dfu restore. I rejailbroke, and then I downloaded an app that required Rock, okay, no biggy, I'll just type in my account again. But then I realized it said Associated RockIDs. ??? How can this be, a dfu restore completely removes everything! So now I'm starting to think, that when you create an account with Rock, that it just stores your serial number, and then when you reinstall it, it checks it's database for a match. Is this how it works, or is Rock leaving behind a jailbreak trace? Thanks!

Maybe associates it with your imei number.

this has also happened on my ipod touch, does the ipod touch have an imei number too?

Probably your UDID identifier number
Click on your iPod Touch or iPhone tab, then look at the Summary page. Click on the serial number and it should switch to UDID

I dont think so.
Maybe another serial ID number.
I wouldnt worry about it.
Its not that it leaves anything behind that a restore cant remove, its something on the Rocks end that is saved on their server to identify your device.

Well, Cydia keeps track of it via UDID. I imagine Rock does the same.
