I have HTC ADR6410LVW and it freezes up all the time..."loading". It has done this for at least 1 full year. I've never owned a smartphone before and this is changing my mind. Why are these phone freezing up?

Thank you to the community members for assisting each other! I can understand the inconvenience surrounding the notifications not being pushed to the device. Are you having trouble with only e-mail notifications? Have you tried to uninstall the e-mail and add back? Go into Settings > Accounts & Sync > Make sure the e-mail sync is on (green revolving arrow). To check your software: Applications > Settings > About phone > Build number. Click on this link for additional information regarding the software: http://bit.ly/rNi1Mw . Does your device freeze during a particular task? Does a soft reset (removing battery) ever fix it? Looking forward to your reply.
Thank you,
