Edit: Just realised I got the thread title wrong - it switches automatically OFF

Hi,

Here's the dilemma.

I turn the iPhone's airplane mode to ON - The carrier and Wi-Fi switches off, as expected.

The iPhone goes off the sleep after the one minute auto-lock.

Leave it for a few minutes (2-3) and press the 'Home' or 'Sleep' button (wake the iPhone up), and the airplane mode switches off the carrier and Wi-Fi reconnect.

It also happens when the alarm rings - airplane mode switches off automatically.

Usually it stays off until I manually switch it off - is this some strange issue?

Thanks for your help in advance
