    What reason would Apple have for a microSim card?
    The physical size of the microSIM reader in the phone is the same as a real SIM reader so there isn't s apace savings reason.

    I only can guess it is a concession to AT&T. In a way it lets them hardware lock the device to AT&T for longer as AT&T will likely be the only ones coming out with microSIM cards for a while. Tmobile will later on, but for the short term, there won't be any unlocked iPhones in the US.

    Any other possible reasons?

    From Wikipedia:
    Long story short... its the future of SIM cards, so Apple implemented them.

    They've been a standard since 2003. Only now Apple are using them. I think it's to screw the unlockers.

    No one will know for sure if you can just shave a regular sim card until the 3G ipads come out.. I'm not sure if the micro sim card readers are backwards compatible, or if there's something in the new micro sims that the iphones require for activation etc.

    This is the easiest way to prevent unlocking. In fact as far as the hardware goes, it is a pretty clever idea. What's the point of unlocking, if you cannot put your SIM in? It would be funny, if networks released some micro-SIMs just to make unlocking viable.

    but why does apple care about unlocking. only at&t does. apple benefits when more iphones are sold to unlockers.

    I'm just hoping that I can slap my micro sim card from my 4g iPhone into my iPad.

    Apple's interest is to CONTROL the situation about unlocking. They can assure networks that they would be able to keep customers, as people wouldn't just buy the subsidised handsets and pay the tariffs to other companies or sell it overseas. Not all phones are on contract.

    So by introducing micro-SIM, Apple shifts some responsibility to networks. I'm sure that it means higher prices for exclusive deals with networks all around the world. And in the US, too. Imagine how much more AT&T would pay for a deal, when they can make sure that they will keep the customers throughout the contract period.

    Here in the UK, unlocking is pretty widespread and so many people bought unlocked iPhones to use them on other networks that I wouldn't be surprised if the idea of a micro-SIM came from the networks and not from Apple. Once there is money in it, of course, Apple is too happy to do it.

    They also take up less space.

    But does Apple/AT&T expect every single person upgrading from a 3G/3GS to go into a physical AT&T store to swap out their current SIM card to a micro-sim?

    That alone turns me off of the whole thing...

    If it does have the micro SIM in it. I would have a feeling T mobile will come out with that option as well.

    X2, making it smaller they can cram more stuff in the iPhone or slim up the design.

    So if they have micro sims in, I won't be able to put my current sim into a newly purchased iPhone 4, because it won't fit. So what do I do? In the UK it will be a HUGE pain in the ass. Lots of people (like me) buy their iPhone on PAYG, and then put their own 30 day contract sims in. If they can't do this, they'll buy a handset that they can surely.

    Also, say I took out a new contract with the new iPhone, and was going to the beach and wanted to pop my sim into my old dumb phone for a few hours. Oh, I can't do that, as it's the wrong size!?!?

    It sounds like most of the components were shrunken in the iPhone to fit a bigger battery. From Gizmodo

    MicroSIM was probably another thing they could use that was smaller to fit a bigger battery.

    Since Apple stores will obviously be selling new iPhones, they will have a stock of MicroSIMs too.

    This really sucks because I like to take my iPhone SIM out and put it into a cheap phone when I go snowboarding.

    well, no one is making you upgrade but i agree. i like being able to have backups. if i keep my backup iphone, i will no longer be able to use it if i happen to lose the new one if i get it....unless there is a micro to reg sim adapter

    Yup. Micro sim allows for more free space. It may not be much to you, but for electronics, real estate is precious. It's a good move because they can cram some more stuff in there.

    They come in the box if you order it online, or I'm sure the Apple store will have a supply to use with the phone.

    When I bought my 3G at an apple store, it came with a new SIM.

    It should be compatible.

    This was a big concern of mine as well(I like to be able to move phones, and the work I do summer I'd rather not have my iPhone), but there are adapters to allow that


    That one is from Europe, but its only 5 Euro, so they'll surely be cheap in the US as well!

    Yes it's a pain that is causes many issues, like cant swap to the old phone when your out in the elements, or other problems outlined here.

    But I look at it as a good thing.

    It's about time a new smaller sim standard is picked up.

    If people complained this much for every form factor change we would be stuck with VHS tapes and Compact Flash cards for digital cameras...

    I get blu-ray movies from netflix now, I used to watch them on my computer and in my car. Now I can't. But I still got a blu-ray player. I am upset many of my older devices that play DVD's are now unusable.

    Yes I know the blu-rays are a bad example, because most Apple fans don't care for Blu-Ray. But you get my point.

    It's a problem now, but as more devices and carriers pick up micro sim's The conversion and compatibility issues will go away.

    Also look at how many people complained about 64bit computing over the years. Now the 32 to 64 bit migration is painless, and the advantages of 64bit are showing.

    I'm excited to see micro sim, I will thank micro sim for my new larger battery.

    No. I have stood in line for every iPhone released to date. Apple has never swapped sim cards. The phone already has one installed. They simply deactivate your old phone and activate your new one.

    Well lets say for a moment... that my iPhone is owned by my employer. I was planning on buying the new 4g and swapping the sim card from my old phone to the new phone.

    Technically, they can't cancel the line, because i don't own the line.

    How would i go about this process now that these stupid micro-sims are in the phones.
