General rule is that once the seatbelt sign is switched off, moblies can be used in flight mode.
However on descent, when seatbelt sign is switched on, ALL electronic devices are supposed to be turned off.

I've had similar experience to Mach Tuck, and text messages were from Russian service providers, too
That was my 'old' 3G unit, but no repeat with iPhone 4. Be careful with the previous advice about holding both buttons, that is the Apple shortcut to a master reset.....

All electronic devices that do not have a physically moving on/off switch which sits in different positions when on or off, not just a button, are never truly off. They have to have residual circuits on to recognise the button press to turn them on.
The only way to truly turn off any mobile is to remove the battery, and this is not possible to do with an iphone.

Apple tech support would beg to differ with you. If you hold the power button down long enough to get the red slider, then slide it, the unit is indeed fully powered down at that point.

No, otherwise, how would it know to turn on when you press the button.
The button you press is a "soft" switch, not an actual switch.
If the switch physically moves contacts that either remain closed in one position, or open in the other, then it is "off"
Otherwise it is just mostly off, and an iphone is less off than most.
A very short google will explain most of it. When you see bad guys in movies remove the batteries from their phones, they are not just making it up. They really have to do it.

Something to think about:
To turn an iphone on, you have to hold the switch in for a certain amount of time.
If the phone is completely off, what is monitoring how long you press the button?

What is sure is that you have to be carefull, when accessing your Email, with the Iphone, you have to disconnect or turn off your Email once you have finish, otherwise the connection to your Email account is open permanently, your Address book is then accessible, and you will end up selling Viagra is the best case, or is the worst case an Email stating that you are stuck somewhere and you need money urgently.
An iPhone, just like every computer, is never truly off. Certain components are going to remain battery powered so things like a BIOS clock remain active and correct.

Unless your E-mail providers are absolute retards any connection you make to your IMAP server is an SSL/TLS encrypted tunnel which is unreadable by 3rd parties.
When the experiment ended, after six months of pain and irritation, it was, needless to say, declared a success. The Blackberry's were collected and there was talk of us being issued iPhones - until it was found the iPhone will not support any form of encryption. If you use iPhone with your email, it is, by definition, unsecured.
