Does anybody use the Trackr app under IOS 5?

I am a little hesitant to upgrade to IOS version 5, since I heard there were some issues with users under 4.3 (I am still a very happy user Trackr under version 4.2).

I did see Trackr is available again in the Apple store, does anybody know if development started again?

I am using IOS5 and so far I have not had any issues tracking or being tracked.
