Great! 0.4.3 is amazing.
First time I can
1. select a photo (selection pane shows latest photos rather fast now, big improvement!)
and
2. successfully upload it to foursquare.
Thank you very much, I am so happy.

One more wish: could Nelisqare scale the size of the uploaded image automatically to some reasonable limit (like VGA size), as the N900-shot photos are too large to be viewed in Nelisquare and take rather long to download? Nelisquare (and all other Foursquare apps) is meant to be used on the road...
Of course I could resize the photo myself using some other app, but that would be quite cumbersome to do...
