By then, there will be enough features in the OS that jailbreaking will not be needed.
The iPhone is already unlocked for Canada. We can use any carrier we want. Bell, Rogers, Telus, Fido... etc. CANADA IS BETTER THAN AT&T!
Umm, I don't think you are correct there. I have both an iPhone 3G and and Apple 3GS, both of which i have bought out. Roger's will not unlock my iPhones so that I can use another carrier when I travel. I can go to "a guy" and get it unlocked, but it stands right now, the CRTC has done nothing to force carriers to unlock the product once the original contract has been fulfilled.
The new iPhone 4 will be available to buy unlocked, and that is a great thing for me in my case, (I live in Panama, but travel back to Canada yearly). The next issue for me will be to find a carrier that will sell me a short term plan that allows me to use all the features of my iPhone (voice and data) without gouging my wallet. Looking at the costs and plans offered to 3G iPad users here in Canada, I don't see how any of the carriers have yet figured out that there is a market for international customers of these products that find themselves in the country for extended period of time. They'd rather try and sell me a ridiculous "International data plan" -- an insane amount of money for little benefit, or better yet NOT sell me the plan and reap huge amounts of cash for using my iPhone in other parts of the world. Jailbreaking and unlocking is not the best option for me, as the Panama carrier (Movistar) will not sell a SIM card to an iPhone not locked to their network.
I am all in favor of anything that can be done to turn this around. Otherwise I have the most expensive iPod in my pocket when I travel, because I sure as hell am not paying the prices they want to usrv the features of my iPhone while roaming.
