But that's cool with users. It's not annoying, it's more or less a one time thing, maybe a hint more if the app is a bit more unusual.
The Symbian notifications? That's a "I hate you, user". Especially the secure connection. Why would it ever ask that?
On the other hand, some of those warnings made sense at the time. Mobile internet was so expensive that I never enabled it. Right up there with MMS one of the things that priced itself out of the reach of regular customers. It was like 3€ to send one single MMS, Internet was also in that domain - per Megabyte (I should note here that the country I lived in is technologically a third world country). That changed only later. So a more modern iPhone and Android could design those things differently.
