I have the Motorola Rockr e8 and it won't receive text messages from the internet. I don't think t-mobile is the problem because i've gotten ringtones and such from t-mobile. But i want to sign up for twitter texting (where it lets you update your status from your phone) and it keeps telling me access denied....

Is it my phone or is it t-mobile? or am i doing something wrong? agh

I also can't receive ringtone or picture messages from online anymore. WTH
