Same here. I've been with t-mo for about 10 yrs now. I got the same deal more or less with 2 yr contract (total after rebate, plus taxes = $214.99). I have had problems with t-mobile where they seriously overcharged my bill by mistake. Of course they more than made up for it (so far,...knock on wood).
One week into 8900 ownership, and I also highly recommend this blackberry to anyone considering the jump to t-mobile/blackberry land. To those users who are willing to wait until their provider gets the 8900 (and/or to those who might try to unlock a t-mobile 8900), I'm sure it will be worth the hassle. Although, if you wait for too long, I'm sure that RIM will release the next new wave of developments before we know it. A positive outcome from this scenario would be more affordable prices for the 8900.
