Here's the scoop. ArduinoConnect is in Appstore review which usually takes about three days. Apparently, the upcoming iOS7 release and all the releases to deal with that (we have one in the hopper too) is driving up the review times to over 8 days at last count. ArduinoConnect has been in for review for 8 days and it is still "waiting for review".
The in-app purchases for RasPiConnect are also in "Waiting for Review" for the past 8 days.
