I have the best android iCloud alternative below but sorry, iCloud for Android doesn't technically exist, and iCloud for Blackberry doesn't either - but here is something equally useful for Android and Blackberry users. This is how you can get the iCloud experience without the ios5 device.
I have an iPad and an Android phone (Samsung Galaxy S). I work on a PC at work and a Macbook at home. So for me iCloud is awesome but useless as it doesn't cross over all my devices. If you are looking for the easier cross platform/device alternative there is a simple answer: SugarSync
SugarSync is cooler or as equally cool as iCloud and Dropbox for the following reasons:
- Works on android, iphone, blackberry, symbian, mac and PC.
- You can choose what folders to sync (dropbox is great but tends to focus on your one dropbox folder)
- You get 5GB free up front
- It has a great online interface
