Dropbox has an Android App. 2GB of cloud storage free. I use it to store all my ROM and update.zip files and apk so that they're always easily accessed and don't have to take up precious space on my SD Card. And I don't have to re-search through a forum to get all the files again. I can download them on my computer and access them from my phone w/o plugging it in or even being near my computer. You can use it to transfer anything from computer to computer to phone. Files edited on one device and saved update on every other device connected to dropbox. But I need (want) MOAR space!! if you use this link to sign up we both get 250mb of extra storage!!!
