Microsoft SkyDrive, the personal cloud for documents, notes, photos and videos, is already part of Windows Phone 7 and the inbuilt Picture and Office hubs. It allows to move files into the SkyDrive cloud that they're available from any web browser anywhere in the world. However, this integration isn't on a surface-level because SkyDrive is deeply integrated into the apps, along with core phone functions. Therefore, Microsoft has released a stand-alone SkyDrive app for Windows Phone 7.5 now which allows to do even more remotely. It allows to to see all folders and files (of all types) and helps to facilitate sharing and file management even better.
It's even possible now to create new folders for a new project or photo album as well as it's now possible to delete old files or whole folders which are no longer used, straight from the Windows Phone. Unfortunately, it's not possible to move or copy files between folders, something which comes really handy prior deleting a folder. Hopefully this is added in a later update!
But that's not all, Microsoft has also noticed that not everyone who uses SkyDrive of a PC is also using a Windows Phone. And following the long history of supporting iPhone customers with built-in support for Hotmail and with apps like Bing, Messenger, OneNote (with SkyDrive sync), and Skype, Microsoft has also released a SkyDrive app for iPhone, which is now available in 32 languages worldwide. In addition to their OneNote notebooks, iPhone customers can now access all of their files in SkyDrive, create folders, delete files, and share links to folders and files directly using the Mail app.
Now it also needs a Windows Live Mesh app for Windows Phone, Android and iOS. Once, when Live Mesh was in Beta, Microsoft had a great one for Windows Mobile and even Mac OS which fade away later. Alternatively, it would be an idea to integrate Windows Live Mesh as an additional service into SkyDrive.
Both, SkyDrive for Windows Phone and iPhone are now available from the Windows Phone Marketplace and the iTunes App Store.
