I've always used AIM to send and receive text msgs to cell phones. It continues to work fine with the two HTC Evo shifts I set up with Sprint in April of 2011. However, my daughter just set up 3 new Evos and an Evo Shift with Sprint this week (June 22nd 2011), and I'm unable to send text msgs from AIM to any of those phones. It worked to the phone number she had yesterday morning before she activated her new Sprint phone, but it won't work now. Totally sucks because I send msgs from my IM client (Trillian) all the time, and I have no idea what could be done to fix this.
