Having Issues with Texting

[LuisT#IM]

Alright, so I got my iPhone this month (1st Generation) and I'm using a T-Mobile Sim Card with it. It was unlocked with BlackRain (bootneuter).

It seems like there is a problem with texting. From one of the people on my contract list, I can not get a text? He'll get most of my texts messages and Ill get some of his too. He has an iPhone too?

Is there anything that can resolve this? Should I remove my sim card or something?

It seems like he's the only person its happening to.

if it's only happening with him it sounds like it's on his end

This might be a dumb question but do you ever see the red exclamation sign ?
