Yeah theres a couple. The best one I browse often is SprintUsers.com Im sure you'll like that one. Tips, advice, plans, experiences, phones, pretty much everything is covered. Hope this helps! 😉

I prefer the official Sprint Blog located here:

http://community.sprint.com/baw/community/buzzaboutw ... »

I find the information there is more accurate, and in addition it is patrolled by Sprint employees who can assist with support when needed for account specific issues and troubleshooting.
