Ok, so I pre-ordered the iPhone 4 32 GB here in Florida but did not expect them to sell it to my since I have an AT&T wireless corporate account (meaning I work for a company that pays for my phone and I cannot edit my account, that company is not AT&T). I arrived near closing (no line) with my pre-order information and he began to ring me up. At the activation process it errored out stating I have a corporate account. I stated I want to buy it for $699 outright and they initially said no. I argued and finally I walked out with the iPhone 4 32 GB for $699 + tax. My receipt stated "No AT&T service activated with purchase". Now, I have a corporate AT&T wireless account which is a regular SIM. I CANNOT change or update my corporate account or SIM so I am considering filing down the SIM into a Micro Sim and using it with the phone. But, will I have issues activating the iPhone via iTunes? My ICCID number on my corporate SIM is different than the ICCID on the micro sim in the iPhone 4 box. Does this matter? I am not opening the box until I hear a story of someone else doing something similar. I simply want to activate the iPhone and use my existing corporate account which has unlimited data and is paid for. Thanks guys! Dallas.
