Jailbreak Issues

[Rameen]

I still am unable to jailbreak my iphone with the new iTunes version installed. I know a lot of people on here have been experiencing the same "Illegal Insstruction" issues while attempting. Has there been a fix for this problem yet??? I have been unable to mod for weeks now and it seems noone can fix this.
How do I go about changing my icons/dock image without using jailbreak?

Someone help me please...!!!!

What if I want to just send some simple image files over, not large packages of applications??
