I am considering exchanging my 3 week old 32 gb ipad 3 (wifi only with ios 5.1.1) for the larger 64 gb ipad3 (wifi only) because I need more space. I recently purchased the 32 gb iPad just prior to iOS 6 release. Fortunately for me, Best Buy allows for exchanges like this within 30 days of purchase. If I make this exchange, will the new 64 gb ipad force me to upgrade to iOS6 when I initially boot up or will I be able to keep 5.1? After reading of the numerous problems people seem to be having with iOS 6, I really don't want to upgrade until all these issues are sorted out. I absolutely LOVE my ipad 3 with iOS 5.1.1. If the upgrade is inevitable, then maybe I'll just keep my 32 gb iPad.
