If you do end up posting on the Sprint site please do post in this thread as well...
Also it was just pointed out that there also is a Samsung support Twitter @ www.twitter.com/samsungsupport
(Please also contact there if you experience LOS)
If you would like to follow this up with a call to tech support, it will help. Try and get transferred to advanced tech support.
This needs to happen from as many people experiencing this as possible!
Don't be lazy!
