It wont be fixed I'm afraid @jeanpierre2 as there isnt anything to fix - nothing is broken, its a decision the company (and many others) have made to not support out of date operating systems
The operating system is no longer supported and as such Dropbox wont work on it unless you already had an older version installed. If it wont work connecting to other systems (GoodReader for example) that is them restricting things.
