Does the following sound familiar: you rushed home with your new iPhone, plugged it into your computer, loaded up iTunes, and started zipping through the activation process. After selecting a plan, perhaps setting up an iTunes account, and agreeing to a few sets of terms - you were just about ready to use your iPhone. Then, it happened. "It", in this case, refers to the "your iPhone activation requires additional time to complete" message that seemingly countless iPhone customers have received.

Subsequently, users who receive the wait message receive an email from Apple's iTunes store which states the following: "AT&T is now processing your activation. You will receive an email confirmation once your activation is complete."

There are mixed indications from AT&T about what is causing the delays. AT&T representatives have suggested individual account issues, overwhelming activation volumes, and delays related to porting numbers from other networks. Though most customers who have actually gotten to speak with AT&T customer service (hold times are over an hour in most cases) report being told they can expect a 2-6 hour wait, some have reported being told they may not have their iPhones activated for 24-72 hours.

Most customers who are in the activation waiting period have also already had their existing phone's service disabled by AT&T, further increasing the frustration involved in waiting.

It's worth mentioning that the iPhone is, in a sense, useless without activating it. Short of being able to make emergency calls, there's little one can do with their new iPhone except play with the unlock slider on the "Activate iPhone" screen. And folks, despite those who might feel like it is, your iPhone not being activated is NOT an emergency - so please resist the urge to call 9-1-1 and complain to them. Besides, they can't help.

For those of you that have contacted iPhoneFAQ looking for answers to these activation issues, check back to this post, we'll update information here as it becomes available.

(Updated - June 30th, 11:20am EDT) AT&T customer service has indicated that pre-existing AT&T customers waiting for activation with their previous phone already disconnected can remove the SIM card from the iPhone, place it in their other phone, and use that for calls while waiting for thieir iPhone activation email. According to AT&T, doing such will not interrupt or affect the waiting activation.

Disclaimer: we're not supporting this information from AT&T or suggesting you do anything but wait. However, for those of you who may need to place urgent calls, this may be an option to exercise.

(Updated - June 30th, 11:08pm EDT) At this point we've been lucky enough to get the two iPhones we've been struggling with getting activated actually up and running. Unfortunately, there isn't one particular solution we can suggest to any of you. Both are live now as a result of one thing and one thing only:Â persistence.

Each phone took over 24 hours and 10 calls to AT&T to get activated. On almost every call, the AT&T representative on the other end identified some culprit or another holding up the process. We're confident, at least with these two particular phones, that without interaction with the AT&T staff, activation would not have completed.

Be sure to do the following:Â get your order number (even if you didn't get this in email, a rep should be able to give it to you), ask about "holds" on your account, verify IMEI and SIM card numbers, make sure nothing on the account is "awaiting verification". Keep checking your activation status and speaking directly with iPhone activation support.
