So I have had this weird problem where both my wifi and my cell data just stops working or goes mega mega slow. Both signals stay up so I have no indication its happening besides safari or other apps just not loading data. I have figured out if I go into settings and turn airplane mode on then off it resets everything and stuff starts working again. Has anyone else had this problem? Do you think apple would replace this phone / fix it if I brought it in? Like I said before its pretty random so I am not sure I could reproduce it for them in the store unless I walked around the mall until it happened and then took it in.
