Hey guys,
I have a 7730 with t-mobile, and downloaded the at&t 4.0 like they said it would work on the BlackberryForums.com. I havent had any problems, but the only one i have had is the SMS. I have tried to reply to SMS i receive and also create one but yet nobody gets it. Why does this not work? It for some reason is trying to send it as an email maybe?

Somebody please help me.

Thanks!

More info please? How are you sending the message? How large is the message? Any error messages or status icons next to the message that might tell a problem?

I simply received an SMS message from someone, hit reply and typed in hello can you get this? and sent it. I get the green check in my outbox and everything goes ok, they just never received the text message. I tried this on about 10 different phones with 4 different kinds of service.

Also tried to "create sms" message to someone and still the same result.

This stinks really bad!

I would contact TMO to make sure you aren't missing anything on your plan you should have. If everything is sent fine from the device, or you reply, this this sounds like it should be a carrier issue.
