Problem with iphone (unlocked 5)?

My iphone stopped working, so i swapped it out at the store.

the old issues are gone, but there's something funky with the internet:
when i go to the app store or the itunes store to look at the top 25 for example, it just says too many http redirects. It also doesn't remember Wi-Fi networks and sometimes when i'm at home it disconnects randomly…

any thoughts?

How to find my lost iPhone 4s?
