Ok. I recently jailbroke my iphone 3g to see what it was all about and was really impressed. I learned alot (thanks jmann) and I am now in awe even more about what this great device is capable of. I did a restore because I wanted to wait for the 3.0 software to come out before I got too deep into cydia etc..and then just have to start all over in a few weeks. That being said, I see people suggesting to use "restore dfu" in order to restore. I simply used the restore button on itunes. Two Questions: what does dfu restore mean? (please just dont tell me what it stands for...explain a tidbit). And is it ok that I used the regular restore? Like will that have any repurcussions when I download siftware 3.0?
