Hi all, I've been using android phone for years and just purchased my first iPhone today. I've had iPads for years(wifi only) but am new to the iPhone. My question is how does the iPhone handle data when connected to wifi? Does all data except phone calls and maybe some texting default to wifi instead of cellular when the iPhone connects to a wireless network? On android this was the case. At home when connected to wifi all my web surfing, email, app usage on my S4 automatically went thru wifi. When I left the house it reverted back to cellular. It was dead simple. If I'm understandingright the iPhone and iOS is not like that? I have to go in and specify which apps I want to use wifi and not cellular? If so this seems ass backwards to me and a major downside. Any application on an iPhone should default to using wifi if it is available with out me having to go in and specify for every single thing? If this is true I kinda regret purchasing this already. iOS is supposed to be known for its simplicity.
