Looks like we now have the ability to save and backup your Flex tweaks and this is 100% free.
What this standalone app lets you do with your Flex and Flex 2 tweaks is send them to your drop box. As well as restore them if need be. This is also a great way to share your Flex tweaks with friends.
So if your a Flex or Flex 2 user this is a great app for you. And I would suggest that you make your way to Cydia and install CloudFlex today.
