I agree. If it was less than 4 months the OP should wait, but 8-9 months no way.
If he is currently with ATT, I don't see what the prepaid options have to do with anything. Or the statement about going without a phone. You can continue to use your phone out of contract unless it is broken.
The question about liking to get a phone when it is first released means he has to wait. If he got one now, it has been out for months. And if he is willing to buy a phone early, again, he should have done it months ago.
In my case, I bought my first iPhone in late November last year. Of course, I knew a new one would be coming out in only 7 months, but I was finally eligible for a subsidized price. But I don't plan to rush out and buy another in June. Absent, of course, loss or damage.
