Hi all. I just purchased my Eris earlier in the week on the Verizon network. I have not been able to receive any text messages from my friends who are using AT&T and Sprint. They receive mine, but I do not get their's. I can receive text messages from a friend who uses Verizon. Verizon said it was my friends' problem and not theirs. I installed Handcent to see if that would help, but it did not. Any suggestions on what I need to do? Thanks!
