I havent seen this discussed anywhere else, so for those that didnt know, Dropbox is now 3.0 compatible. For those like me who were pissed to find out you had to upgrade to use this wonderful application.
The reason everyone complained about its lack of 3.0 compatibility was that there was no 3.1 jailbreak at the time so we had to wait for either that or Dropbox. 3.1 jailbreak came so we're fine.
Funny, this is the app that made me go to 3.1, kind of annoying to have o wipe everything to re-jailbreak but I couldn't live without my 3rd party apps.
