Tumblr for iPhone Updated for Retina Display & Background Processing

If Twitter’s 140 characters of text is too limiting and conventional blogging platforms seem like too much work to maintain and use, you might want to take a look at Tumblr’s free tumblog service that lets you quickly and easily share your thoughts via text, audio, images, or video from a variety of sources. I use it, for example, to collect video recordings and other content I create on a variety of sources like YouTube and Qik.
