Iphone temp with/without case

Hey guys,

I've noticed that my iphone runs MUCH hotter with my incipio NGP on. I had being playing for 3 hours straight, Blooms TD and really runs pretty cold!

- So do you guys feel the same with a case on/off?

- Also, is there an app to monitor my iphone temp with no jailbreak?

- And finally, is it dangerous to run my iphone at a higher temp when using my case?

Thx in advance

 

Bump, anyone?
