Can you move your icons around? Yes. Can you do it like the 1.1.3 firmware with the app package? No.
If you just want to rearrange for now, you can download Customize (and make sure you download at least one theme, so the program doesn't continually crash) and tap the "Icon display order" submenu. Then drag icons up and down the list as you please.
Hope this helps, and hopefully an easy and official 1.1.3 Jailbreak will become available soon.
