    I understand that unlocking an iphone allows it to be used with other networks such as verizon, or t mobile, but does it serve any other function?

    just wondering...

    Besides voiding your warranty, it gets you out of the 2-year agreement with at&t and as you said it lets you use almost any GSM network... o and you loose visual voice mail and any type of "backup" by Apple. That didn't stop me from unlocking mine hehe:D just love it! Hope this helped.

    it doesn't technically let you get out of a 2-year contract with at&t, but it does let you *avoid* getting into a contract with them if unlocking it is the first thing you do. if you unlock it after you activate it with at&t and switch to a t-mobile plan, at&t will still charge you the contract cancellation fee...

    and in the u.s., the only other cell carrier you could use with an unlocked iphone is t-mobile - the other carriers (sprint & verizon) use cdma technology, which is not compatible with the iphone's gsm radio...

    oh, ok, i was just wondering if it let you add any other specific feature to the phone, because I'm with att right now, and I'm not planning on leaving, but i want to be able to add different apps, can i do that on a "locked" phone?

    you are confusing unlocking and jailbreaking.

    Unlocking = use any GSM carrier
    Jailbreaking (hacking) = using 3rd party apps of your choice

    Yes, you are supposed to be using AT&T.

    Jailbreak actually fake activates the phone allowing you to use it (without service) like a PDA. Then you can download apps for it such as the unlock program...

    Jailbreaking, without subsequent SIM-unlocking, doesn't have any impact on your ability to use somebody other than AT&T.

    And so far, iPhones that have only been jailbroken (but not SIM-unlocked) have not lost any of their manufacturer-approved functionality as a result of firmware upgrades etc from Apple - although any 3rd-party applications that may have been installed while the phone was jailbroken may be deleted.

    However, the act of jailbreaking the phone can be very easily argued to be just as much a violation of Apple's EULA as SIM-unlocking is. That, depending on the validity of the contract in your jurisdiction, may constitute a breach of contract, for which you may lose access to warranty services, and if the contract allows for it, you may be required to pay fines.

    (I have in the past been persuaded to consider that jailbreaking, performed in isolation, might actually be a more serious offence than the SIM-unlock process. Circumvention of technological security measures is an offence under the DMCA, independent of any violation of copyright that you may or may not commit following the circumvention. There is a temporary exemption on the books that bypasses this prohibition, if the circumvention is done solely with the intent of obtaining wireless network interoperability. Jailbreaking, except when solely utilized as an intermediate step toward a SIM-unlock, might therefore be considered a violation of the DMCA. That'd be a crime that could land you in jail.)

    It has been suggested that it ought to be possible to revert any simply jailbroken (but not SIM-unlocked) iPhone back to its original factory state. So you may be able to safely obscure the fact that it had been modified in the past, thus maintaining access to warranty services. Your mileage may most certainly vary on that point though.

    I didn't know this forum "owed" you an answer.

    The iPod Touch doesn't get "free" internet. It uses WiFi which you usually have setup yourself (or leech off a neighbor, or a Starbucks, etc). Yea, if you buy an unlocked phone you can get service from a carrier without a data plan. But you won't be able to use the internet without being on an active WiFi network.

    Yea that's how it works on the iPod Touch and any other "iDevice" that doesn't have a data plan. Texting is not part of the data plan so as long as you have a texting plan you'll be able text whenever you have a cellular connection.

    And if you use it on AT$T in the US, they "may" add the internet to your plan and charge you for it, whether you want to pay or not. Some have had it added without their consent as it is stated in all of the contracts fine print that the iPhone usage on their network requires the addition of a data plan.
