There is a new tweak on Cydia: Safari Upload Enabler. I've done an overview of it here: Safari Upload Enabler - Upload Photos & Files Directly
Yes, I am shilling my own post. But, I wanted to make sure y'all saw this new (and nifty!) addition to the jail break world. And, you might have missed it - hidden as the overview is over in the tweak section.
It's so cool - and so much what everyone has been asking for - that I had to make sure you saw it.
