Thats the thing. An iPhone will not work on verizon period.
To my understanding you would have to make the iPhone OS accept any SIM (at the very least). Isn't that illegal? That's the only way it would seem to work, using a warranty voiding hack.
Just cruising around on the internet seems to suggest that messing with the hardware inside (somehow making CDMA work also, such as in some Blackberrys) is a way to do it. No thanks, not for me. I will leave that for the EEs here or super hardware geeks.
It was hard enough working the insides of a laptop. I maxed out my iBook's RAM a long time ago but I heard about a third party RAM maker I never heard of who made a larger capacity RAM module which worked on the old rev. a clamshells. Some iBook users went for the suspicious RAM with varying results. It wasn't until a reputable RAM maker made a proper, capable module that most were OK with going over Apple's recommended limit of RAM for the 160 MB RAM maxed out rev. A iBook. I was happy with 160 megs of RAM in 2000, so I didn't feel a need to stick some unknown 256 MB stick in it and possibly damage something in the iBook I just paid $1599 for.
I say if your area works with AT&T, get the iPhone and be happy it works. Let's assume it's possible to "easily" make an iPhone work with another carrier, would it really make the iPhone have that much better reception? And if the reception is better, don't you still have to pay for the existing AT&T contract or spend a lot of money opting out?
It just sounds like a geek thing for the sake of it.
It's like on the site
www.woz.org where somebody took out the guts of an old CRT iMac and put it into a large 24" inch Sony CRT and made basically a hybrid iMac with Sony CRT. While it's possible, it doesn't offer up any real advantage and it can be dangerous. It's one thing to be taking apart LCDs, but completely another thing to be digging around inside a CRT where there is a chance one can get severely shocked.
As a techie for a decade, I learned that not everything possible is legal, safe, or practical.
The Wall Street Journal now thinks its likely Apple will officially have Verizon. Personally, I don't care since I just need a basic cell phone. If I wanted games and a better internet experience on the road, yet not have a laptop, that's what the iPad is for.
But since this isn't a thread about jailbreaking, Verizon, iBooks, or iPads, let the debate on iPhone 4 continue, right? Hey at least we care unlike other customers and we are a small part of why Apple works. They tend to listen to us (the buying public) and make any necessary fixes or changes.
