Hey, I was gonna downlaod some multimedia app in rock/cydia and all of them were prompting me with warning messages about having a 4.0.2 firmware. I jailbroke my device on 4.0 (i'm not 100% sure, is there anyway I can check that? it might have been in 4.0.1 if that is possible...). Am i under any risk? May I download these apps? Thanks.
