So I plan on purchasing the next iPhone during the pre-order stage as soon as it becomes available online. I currently have been grandfathered into a text plan on AT&T that is no longer offered that I do not want to lose. (1000 texts a month for $10.) I'm pretty sure that if I attempt to pre-order on Apple's site then I'll be forced to select from one of the current text plans offered by AT&T. My thinking is that I'll be able to keep my current text plan if I pre-order through AT&T's site instead. Is this true? Also, will I be able to simply pop out the sim card on my iPhone 4 and place it into the new iPhone and have it up and working with no issues or do I need to call a number to activate it? Thanks.
