iPhone cannot text one specific number - help appreciated?
So the problem is that I cannot text one specific number (that I text on a daily basis); or rather the text is not getting through to that number... We can call each other and they can text me; but whenever I text them the SMS seems to go through fine on my phone but they never receive it. Texts to other numbers seem to be getting through fine and it happened pretty suddenly.
Any suggestions? I have already performed a Network Reset in the iPhone settings. Could this just be an issue with T-mobile? If so who should I contact about it to alert them - their 'customer care' team?

My info:
Phone - iPhone 3G with the latest software update that is commercially available through iTunes (I think that this is OS 3.1.3)

Thanks for any advice you can offer.
