My ipad2 is running on ios4 and I need to update to 5 or 6 as lots of apps won't run on 4 any more. I can't do it wirelessly as it doesn't have that option on my phone.
When I connect to my mac and go into iTunes it tells me I need to update the iPad software but it downloads it and them gives me an error message telling me the software file is corrupt. I've tried restoring to factory settings and get the same message. Does anyone know what I need to do?
