Cloud storage provider Dropbox has just doubled the referral bonus it gives users for referring friends to the service. Previously Dropbox referrals resulted in a bonus of 250MB for both the referrer and the new sign-up, but from today that's been increased to a more substantial 500MB. Similarly, the maximum amount of storage users can earn through referrals has been upped from 8GB to 16GB. If you're a paying user, that's doubled again to 1GB per referral, up to 32GB total.
There's also good news for anyone who's already referred a bunch of people -- your bonuses from those referrals will also be doubled, so you'll likely see your Dropbox allowance increase a little.
Dropbox continues to offer generous amounts of storage for users willing to plug its services to friends, or help with the testing of new features. Recently launched an automatic camera upload feature, and credited testers with 500MB for their first upload, as well as 500MB more for each 500MB of automatic uploads. The company's also partnered with some leading smartphone manufacturers, including Samsung and HTC. The HTC One X and One S launche tomorrow with Dropbox built-in, with an extra 23GB of storage for HTC One users.
