Dropbox is offering a free 3GB of storage for trying their new desktop Beta programme (1.3.4 or higher) or by using their new Android app.
This seems to be a repeat of the offer that first appeared in February.
I tried it then & the extra storage I gained is a permanent addition to my account. All I did was load up a flash pen with a load of pics & let it uplaod, easy peasy.
All you need to do is use their new picture upload service to upload 3 GB of pics. For every 500MB you uplaod they'll give you 500MB for free.
Like I said, I tried this last month & it was very easy.
This still works!!
