I have an iPhone and it's unloacked and the reason is simple - I live in Canada. I did the Windows/Blackberry thing for a long time and last year made the move to a Mac. It has been a whole new computing experience and a very welcome change. When the iPhone was announced I was ecstatic - an Apple device to replace the Blackberry! But no iPhone for Canada......
When it comes to GSM in Canada, there is only one game in town - Rogers and they have shown absolutely no indication that they are planning to release it in Canada so I got one (thanks SC) and unlocked it. It has been everything the Mac switch was and there is one huge benefit to me. Data rates in Canada are hugely expensive so the WiFi capability of the iPhone is a major benefit to me. My data usage has gone down about 75% since I started using the iPhone mainly because I can check my email at the office when away from my desk and at the airport where there is a hotspot ( I work in airline security so I spend about 30% of my time at the airport). Also at home I can do a quick check of email without having to fire up my computer.
So while I have an unlocked iPhone, it is not because I am trying to screw Apple or AT&T or anyone else. If and when Rogers releases the iPhone I will be first in line, but until then I will use it unlocked. The rotten part is with Apple actively trying to stop the unlocks, I can't get the new features and my big question is will leopard be a problem (i.e. will I "have" to update the firmware for it to talk to my Mac).
The iPhone is not just a phone to me, it is a better way to communicate just as the Mac is a better way to compute.
So I'm unlocked and "feature-locked" until Rogers gets off their asses and/or Apple realizes the world doesn't end at the 48th parallel.........
And there are LOTS of people like you. I will be moving back to Europe in the Spring to a country with no iphone sales and I'll be in the same situation. I hope that Apple at the very least won't restrict the syncing with itunes. I guess as long as we don't update itunes we'll be fine, but as you said, what happens when leopard comes out? Will they force us to update? I hope not. And let's hope the world's iphone hackers see this all as a challenge.
Also, for those who talk about unlockers trying to screw ATT or Apple - what BS! the reason this is all happening is because Apple and ATT want to squeeze every drop of money out of each consumer and give as little as possible. We're just defending ourselves!
