Yes, you read it right.
This time, we work around the 23GB of extra space for 2 years, that originally applies to Sense 4.0 phones.
How-to
Step 1: If you already have Dropbox installed on your Android device, you must Clear data, Force close and finally uninstall it from Settings > Applications > Manage Applications > Dropbox.
Step 2: Download and install the Dropbox+23GB APK. Be sure to enable Unknown sources under Settings > Applications or Settings > Security (on ICS) before installing the APK!
Step 3: Launch the app as usual and log in.
Step 4: Wait for the confirmation email.
• If you haven't received the confirmation mail after 30 minutes - 3 days, try uninstalling the app, the installing it again and login. BUT, it doesn't work for everyone. Haven't figured out why yet.
• After getting the extra space, you can go back to official dropbox builds (uninstall mine first).

My phone is a SGS2 on ICS
I tried this on the 27th of March, and got my email today in the morning. It will take time so if you want to test it out before voting, fine with me.
If you don't have a dropbox account, feel free to use my referral

Finally if you feel this isn't really a deal, Report it to the mods in the options below.
Confirmed working on my SGS, did not need to wait for confirmation email.
