I just got a brand new 6230 off of ebay and it seems that every 12-24 hours the phone freezes or "hangs up"..similar to a software program. The only way to get it working again is to take the batter out and power it back on. Is this a software issue? Will nokia replace or fix this phone, since i did not buy it from cingular (although it is a cingular version and all). I have never dealt with them in a warranty repair siutation.
