TP2 is not working, what to do?

[thebeerbandit]

I have insurance with Sprint. My internet is not working unless I use the Wifi on my home network. Also the End Call button is not working when I press it and sometimes when im doing something on my phone it will be activated and close out what im doing or end my calls. Should I just take it in and get a new TP2 or should I wait until they are no longer making them so that I can get a newer phone? That is what I did with my original TP. It was acting up and I took it in and they gave me a TP2 because the TP was no longer being made. Any suggestions would be greatly appreciated.
