Hello all I have seen many posts that are getting quite old now about the pros and cons to upgrade to ios 8 on various devices. At present I have an ipad 2 64gb with wifi and 3G which is currently working on ios 6. Over the last couple of months the ipad is becoming slower when opening apps, especially the Facebook app that requires a few attempts to open, which is very annoying as other apps are linked to it. Safari is also taking a while to load up compared to how it used to be. Question is do I upgrade to ios 8 from 6 in the hope that this sorts the problem. I know the latest Facebook app won't upgrade any further as it requires ios 7. Or do I keep it as it is to sell it with ios 6 and buy a new ipad air 2? Any suggestions would be great, I don't link the ipad to a PC as I keep it as stand alone device which suits me nicely to.
