Be wary that there's a difference between Recovery Mode and DFU Mode . The steps to get into these modes are also different. The differences are :

Recovery Mode :
- Done by holding Home button while connecting the dock connector
- Screen will display iTunes icon and the USB cable connector
- Can be reversed back to normal mode using certain command lines or applications like iBrickr and ZiPhone

DFU Mode :
- Done by FIRST docking the iPhone, then holding both the Sleep/Wake & Home button for 10 seconds, before releasing ONLY the Sleep/Wake button and continue holding the Home button until your Mac/Windows PC sounds an audible beep signifying a new USB device
- Screen will display NOTHING, as if it were switched off. iTunes will still recognize it in 'recovery mode'
- Cannot be reversed or kicked out of, MUST be restored in iTunes

Hopefully this helps clarify any confusion which may have been on anyone's minds regarding the 2 different modes.

ZiPhone would have the most simple and elegant solution, with the big "DFU Mode" button in the GUI. But apparently it didn't work for me, and kept throwing it into Recovery Mode for some reason unknown to myself, had to use iBrickr to kick it out of it. To differentiate between the 2 modes, the iPhone will not have anything on the display when it's in DFU mode, as if it were turned off. It's worth a shot though, as there's still no better method to do so. Good luck!

I believe he's referring to the stage of putting his 1.1.4 phone into DFU mode prior to the upgrade to 2.0, mate ZiPhone doesn't work on phones already running the 2.0 firmware, indeed.

There you have it, TS. 2 alternate solutions to your problem, a simple choice between ZiPhone or +iLiberty, both widely available online. One of which is bound to help you with you DFU dilemma.

P.S. How'd you 'break' your Sleep/Wake button? And by 'break', is it physical damage or the button no longer works? I shiver at the thought of having to leave your phone on at all times or having to switch it off after every call and message. It'd be a living nightmare for any phone's battery lifespan...
