We LOVE Flickr and have pretty much given every Flickr app a serious try (btw, why hasn't Flickr itself released an app?) ... the one we settled on and use exclusively is Mobile Fotos ... why? ... some really unique features: It was the first app to upload the image's EXIF information - love EXIF techie stuff, so this is huge! Also upload GeoTagging At the time, it was the first Flickr app to upload the full size of the image while other apps limited the dimensions of the picture uploads and many more features ... check out the app's description on AppShopper > http://appshopper.com/photography/mobile-fotos Now Mobile Fotos has become even better with the latest update on 1/13: > UI has been re-worked, its awesome > Background uploading que > Much faster download time, user can view images much quicker > Multiple account support - love this as we have several flickr accounts > Integrated Twitter service via built-in web browser, Tweetie, Twitterrific, Twittelator and Twittelator Pro > and more ... So if you love Flickr and are active of Twitter .... Mobile Fotos is certainly worth checking out and is 100% anti-KRAPPS Certified!
