The Boy Genius is reporting that Sprint could offer a CDMA version of the Samsung Galaxy Tab as early as November. There is little else to go on at this point unfortunately.
Past rumours have suggested that Verizon could also offer the Galaxy Tab.
Yesterday, Samsung Canada confirmed that the Galaxy Tab would be available here by the end of the year. That makes availability south of the border around the same time pretty much guaranteed.
Update: The Boy Genius has landed another tantalizing bit of information: The Galaxy Tab from sprint could be a 3G/4G device!
