Just to keep everyone informed as to what's going on with the 1.7 update. I submitted 1.7 for approval to the iTunes App Store on May 10th. A few days later I decided to resubmit version 1.7 to correct an issue that came up in late testing. It's been 6 days since that last submission. 10 days in total. Rumours are that it's taking just over 10 days to approve app submissions. So by that I would estimate version 1.7 will be approved either any day now, or in about 4 or 5 days. However, that doesn't mean that Apple might find some issue with it that they want me to fix and resubmit.
Unfortunately with this system, that's the way it can go. It might take a couple of tries before it's finally approved. But I'm crossing my fingers that they haven't found any serious issues that need correcting and re-submitting.
