I agree with Delta on this. I don't care what a jailbroken iPhone can do, because I can't buy one. I can only buy Apple's crippled iPhone and then crack it. But suppose the next firmware won't allow to be jailbroken in a timely fashion. Of course given enough time any software can be cracked, but what if it takes a couple of months? People are going nuts over Nokia's lengthy repair process for the N900, but Nokia is actually taking in broken phones and fixes them. Apple will destroy your phone ON PURPOSE.

Having to regain control of your own device every single time you update the firmware is EVIL. It's sad that you're willing to put up with it, and actually reward Apple for their behaviour. They got paid for every single iPhone they shipped, so to a large extent they don't care if you jailbreak yours.

Anyway, that's my take on it. Pretty much the only thing that will make me consider switching to an iPhone is if it gives me BJs every morning. And even Apple hasn't invented that technology yet.
