I'm in Houston too and haven't noticed this problem. 'Course I don't really receive that many calls, but every time I've been on the internet so far I've gotten interrupted when a call came in. And I don't do Wifi much. (You know Houston is going to get city wide wifi, right? I can't wait.)It seems that this issue only applies to some. My calls always come through and it seems that others in the Houston, TX area are experiencing what I am.
Perhaps we need to do a survey of the people that are not having calls interrupting their data sessions and their locations.
I would bet that it is location dependent.
My question is does anyone in Houston have his problem?
But I think kycophpd is right. It won't interrupt you if it's downloading. I'll bet it would do the same thing to you and to me.
If it is location dependent, maybe it's not the location, but just that they sent Houston the good iPhones. LOL Where did you get yours? I got mine in the Galleria Apple store.
