Ok, i know i have asked this many times before but i want to be sure before i buy an iphone 4. If i buy one on ios 5.1.1 for example, and it has never been jailbroken or anything, can i dump blobs, and will they be usable for 5.1.1? I ask because iH8sn0w told me yes, but other people on here have said no. I just want to be absolutely sure. Thanks.
