Is there any reason I should not upgrade to iOS 8.4?
Is there any reason I should not upgrade to iOS 8.4 on my iPad 4 or 3? I have less than 1 Gig of overhead RAM left, mostly due to the number of Apps I have so I can remove some Apps if I need to.
Apple support says it's an iPad 4 (by virtue of its model and/or serial number), but some software (Apps) says it's an iPad 3.
MacBook Pro, OS X Mavericks (10.9.5), 4G RAM, 500G HD, iPad4
