What's funny is that on Apple's own support page for the iPhone it gives clear directions to "remove the sim card before sending the iPhone to Apple for repair and place the sim in the "loaner phone" supplied to you by Apple"...
Then there are instructions for the user to simply remove the sim card with a paper clip...
Too funny what these Apple Store clerks tell people...LOL
It's even "funnier" what O2 tell people. I've now been told twice by different O2 customer services people that the iPhone will work on a 3G network.
It's probably only a matter of time until someone actually buys one on the strength of that advice, travels abroad to find it doesn't work, and sues them for the loss of business or whatever as a result.
Last time I checked it wasn't really a good idea to lie to people about products in an effort to make them buy something.
Honestly I'm being put off the whole thing now, not because of the iPhone itself but the appalling behaviour of both Apple and O2.
