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
• Auto upload of files and photos from your mobile device. Take a photo and up it goes.
• Push files to your phone or iPad etc from online
• Have shared folders and files and photos with other users if you want
• Play/Stream music on your Android mobile phone from files stored in the cloud.

So iCloud syncs your photos and your music and your stuff. SugarSync does the same. Cool huh?

If you sign up for the trial here is my unadulterated honest pitch: Use this link and I get more and you get more storage. I don't recommend SugarSync because I want more storage - I recommend it because it is awesome.
