Eufloria iPhone and Eufloria iPad/iPhone submitted today. I can't say when they will be available on the store but we'll let you know when we know
Anyone with the iPad version will be able to play on iPhone too. There will also be a cheaper, standalone iPhone version though this has less music to keep it under 50 megs so it's downloadable OTA (i.e. on 3G as opposed to WiFi).
We reworked a significant amount of code for this version and squashed several more minor bugs. It's possible some slipped through so please don't hesitate to report them.
I'll post an iOS update sticky thread with the details.
