Hi I have an old Ipad 4 that is still pretty near and dear, works great, the only problem is I waited too long to update it. I am still running OS8xx because it runs out of memory so quick. Now my mail account won't work anymore unless I am at OS9xx but it looks like I can only update to OS 10. I am afraid OS 10 will eat all my memory. Is there anyway to update only to OS9? Will my ipad run on OS10 and still be able to have any memory? Thanks for any help!!
