(if not on there already) other than that sounds like hardware asnd you may have to turn it in...... the refurbs are known to be garbage and i would try to get a non refurb from them and just tell them about all the bad luck with refurbs and be nice but strict about it.... t-mobiile is pretty cool in that type of stuff though, i take care of my moms account through t-mobile and only had to call once asnd thry surprisingly took care of the problems riught than and there. let us know if any of that works for you.
thanks dash for the help but i do have the stock rom on this phone & i already did my 2nd hard reset so that today i could test it in stock mode no apps installed just to make sure that it is the phone because like i said i looks like after bout 30min of use its when it stars acting up
