Oh I'm in the same place (well I'm a 3rd party developer supporting many shops like yours). I've heard from one of the MailChimp guys 4.1 was submitting binaries just fine. I call myself 'An Upgrade Coward'. I'm afraid of Xcode3 breaking even (a couple clients). Probably going to dupe my SSD into the Spinner so I have a working Xcode3 install no matter what. You do know you can install multiple Xcode versions in parallel right?
