How to delete synced photos off of iphone?

I plug in my iphone and it automatically syncs. I got to photos and unclick the "sync photos" it gives me the option to delete the previous pictures that were synced too so i put yes. Then my phone started syncing all of the photos from my pc to my phone and i kept unplugging it thinking i might of misclickled something and i look at my phone and see that some of the pictures from my PC have downloaded, so i plug my phone back in and do the process all over and i let it sync again, thinking it might just download all the photos then delete them, so i let it sync just to find out it just downloaded even more of my photos onto my phone. This is very annoying and i have no more space in my iphone now.someone please help.

I was super hyped about the recent jailbreak arrival since I figured it would let me unlock my iPhone, once in for all!

How to use the scientific calculator for iPhone 4s?

It is Really confusing. The parentheses don't even work? How do you work on the parentheses?
also, I want to write it like 20sin12 for example. [or 20(sin12)] how do I make it work!
and I've learned that if you want to get the cos of 20 (or cos20) you need to write it like 20 then cos.
then there's x(square root sign) y, y^x, 1/x… How the heck do you use these?

btw. I have calculator but sometimes I'm just lazy to find it in my bag and I could make use of this phone's calculator too.
