IPhone syncs with iTunes but nothing changes?

Everything's sync'd fine before, but now nothing changes when I select SYNC even though I've selected new videos and added extra music. I've tried rebooting my iPhone, restarting my MacBook, but nothing changes. I've looked around and someone said to delete all music and videos, then resync. Even after I have done that, nothing happens.iTunes goes through the syncing process without errors, and completes the sync. When syncing is done, iTunes says more memory is taken up but it contradicts with the iPhone's memory storage statistics in settings. I really don't want to restore my iPhone, as its Jailbroken and it'll take me hours to set everything up again. Any ideas? My iTunes is also the most recent one. I just updated it before the sync. Could it be the problem?

Will they ever make a Pokemon game for iphone/android? E?

So mobile games have gotten pretty damn good like Infinity blade all those so why hasn't Nintendo released gameboy games like Pokemon Red, Blue, Yellow, Silver, or gold? I meant I'm sure iOS can handle them pretty well or even make it possible to battle other people online I'm sure they'd make a shitload of money.

How to make my Iphone work without an active sim?

I changed from an iphone to a blackberry, so i moved my sim card to my new blackberry and switched from an Iphone to a blackberry contract. I put an old sim in my Iphone which isn't on a contract or topped up, my apps without internet still work, but any apps which need internet to run don't work? I wanted to keep my Iphone to use my old apps but i need the ones with internet to work. Is there any way i can do this without topping the sim card up or putting it on a contract?

Edit iTunes Library.itl file on a mac?

I recently purchased a new Macbook Air and would like to be able to sync it with my iPhone without the loss of data that's currently in the phone. I've done some research and found: "http://www.iclarified.com/entry/index.p… To be a common solution for this issue. However I can't complete step 8 because Hex edit tells me that it's read-only.

Is there a way around this?

P.S. I think it's really bad planning/engineering on Apple's part for this one-computer-to-one-iphone rule. I understand that this could be a measure to restrict sharing of purchases and etc. But if they could have thought of a way for people to verify that it's the same primary user and that the primary user is not trying to infringe against any copyrights, then that should be sufficient enough to allow people to sync to new computers.

For the amount of effort I've put into trying to get my iPhone to "pair" with this Macbook Air, almost makes me regret purchasing it.
