No iPhone For 64-Bit Windows
Mizled writes "After buying a new iPhone yesterday and bringing it home to sync and activate it, I found out that Windows 64-bit is not supported. Neither XP 64-bit nor Vista 64-bit works with the iPhone. I called the Apple support line and the rep said I needed to downgrade my computer from a 64-bit operating system. I also posted about my concerns on the Apple iPhone discussion forums, but my post was quickly removed."
A lot of apps still aren't supporting 64 bit. Might have been a good idea to ask. That would have been my first question. I have both Macs and PCs so I don't forsee a problem when I make the plunge. Personally I'm waiting for the dust to settle. There seems to be a few issues that are going to be resolved with software upgrades and the service provider wasn't ready for the onslaught so I can wait a few weeks to make the switch.
Join the club, I bet the iPhone doesn't support Linux at all either.
I like Apple hardware but I won't be buying the iPhone. Too expensive, too locked down. FIC are apparently releasing an open phone (the OpenMoko project), if I upgrade any time soon it'll be to the FIC product.

They have two free products. VMware Player can play any VM out there. VMWare Server is their hosted product. VMWare server is completely free, no strings attached and it works great.
Not if you did it the right way at the beginning. MSDN has contained information on this one for quite a time. I remember that back in 2000, when I was writing network driver for Windows 2000, I thought "What are these stupid macros, why I can't just write unsigned int instead of that ugly looking DWORD." Luckily my code wasn't compiled to any 64 bit Windows since I think I unintentionally left couple of mines there :)
But device drivers are just a small part of "iPhone software" what ever that is. I can envision that GUI and data transfer parts are much bigger things. User-space components are much easier to write to be 32/64-bit compatible unless you really don't know what you are doing.
I don't know why Apple can't produce quality stuff for Windows (and many other companies). Or maybe they are and this is just a marketing decision "See? It doesn't run nicely on Windows because Windows sucks. Luckily we have nice OS X here for you..."
You don't know what you don't know.
It's reasonable to assume that- unless otherwise stated- the requirements in Apple's list would be both necessary and sufficient. It's not like it says "see this obscure Apple doc for more details". Apple probably kept that on display in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying 'Beware of the Leopard'...

Not that it is useful to respond to an inarticulate troll, but whatever I'm bored.
There are plenty of reasons to install a 64-bit OS, even if you don't have >4GB of RAM. One would simply be to support larger amounts of memory in the future. If you've just got a new computer, why not be prepared? Seems rather silly to install an OS that you know you can hit a limit on and have to reinstall later.
Another would be that 4GB isn't the real 32-bit limit. There are two limits you hit first. One is the 2GB per process limit. In Windows, virtual address space is divided right down the centre, with 2GB of kernel, 2GB for user (64-bit Windows does the same just with larger limits). This means that no single process can access more than 2GB of memory, since that is all the virtual address space it is given. So having more memory is fine for multiple programs, but if you have a single program that wants more it doesn't do you any good. Another is the 3.somthing GB limit from PCI devices. PCI devices grab memory ranges to use for getting data to and from them. Not a problem when your memory isn't near the limit of the address space, but when you get above 3GB, you run in to it. At work we have a DVR system with 4GB of memory but only 3.4GB is actually addressable, the rest of the address space is eaten up by the PCI devices.
So really if you have more than 2GB of memory, and especially if you have more than 3GB, a 64-bit OS is the way to go.
However there are other reasons too. In 64-bit mode, the processor has some features it doesn't in 32-bit mode. The most notable are extra registers and 64-bit integers. The extra registers are useful for optimising certain complex, but tight calculation loops (like encryption and such). 64-bit integers are useful any time you have a counter that needs to go past 4.some billion. In 32-bit mode, those numbers must be split in to 32-bit parts with a math library and that is rather slow. In 64-bit mode, they can be operated on natively.
What it really comes down to is that 64-bit is the future. We are rapidly approaching 4GB in normal systems, and the need to move over is well recognised. Even Apple is releasing their OS as 64-bit soon.
Perhaps in the future you'll take a bit more time to educate yourself before posting.
No its not.
64 Bit Vista uses the new driver model. It requires code to be done right. The botchwork that programmers could get away with for 32 bit Windows no longer works.
And 64 Bit Vista drivers have to be signed. Which is something that vendors should do for all versions of Windows, its only been a recommendation for like 5 years.
That said, I beleive that to get the 'designed for Vista' logo you have to support 64 bit.
Taking the comment off the bulleting board is doubleplus lame. Makes it look like Apple can't deal with non cult members as customers.

What a shocker.
The official name of the 64 bit product is Windows XP Professional x64 Edition.
That name is not listed on the iPhone page, don't expect it to be supported.
You can't take the sky from me...
