First HTC Aria I got in October-really like the phone, easy to use, few problems...until about March. All of a sudden I stop receiving incoming text messages of any kind. Problem resolves (temporarily) when I pull the battery and restart the phone. I never get the messages that were sent to me, even after I restart the phone. (Unlike when if the phone is just off, I will get the messages after turning back on) Beginning of June, it's become an every day issue, so I go to AT&T store. The guy puts in a new SIM, and 'resets' the phone to the network. Works fine...till the next day, then the same thing. So, I call the warranty exchange number, get new (refurb) phone on Saturday. Works great, not a single issue...until today. Any ideas? I have not restarted the phone, so that they can 'test' it again and see the issue for themselves again. Will they warranty me out...again? This is really frustrating.
