HELP - Having problems replying to text messages

[Guest MitzEclipse]

Hi All,

I am having problems replying to text messages that are outside the T-Mobile USA network. I use T-Mobile USA and I can hit the "reply" button to text messages on my SMT5600 (Unlocked, from AT&T) to T-Mobile messages.

For other domestic text messages from Cingular, Sprint etc... it will work... sometimes. I know for sure I cannot just hit "reply" to AT&T Wireless and Nextel customers. I have to compose a new message, scroll to the person's name, and then write a message.

Basically, it's a pain to do, and if i forget to create a new message and just hit "reply" the message will not be sent.

Is there a workaround to this? Is there a fix? 3rd party app?

Thanks
