iPad 2 WiFi vs Cellular - Crash (Memory Issue)

Hello,

I'm in the process of optimising my App to run on iPad 2 (2nd Generation iPad).

The main issue is memory performance, I used to get quite a bit of memory warnings on the iPad2 which would lead to a crash.

However, after heavy optimisation it doesn't crashes at all now, and I only get the odd memory warning. Although... This is ONLY the case for iPad 2 WiFi only model. If I attempt to run this app on the Cellular model of the iPad 2, I get a lot more Memory warnings, and it crashes a lot more! In fact, it's unusable on the Cellular version.

Has anyone heard of this issue before? Any ideas why this may be the case?
