Tethering makes my 6700 freeze...

[blksprk]

OK, so I just got a macbook pro and wanted to tether my phone for mobile internet. I tried, got it working, started surfing, then all the sudden, the phone freezes... no key press tone, nothing at all. So i actually went as far as to call VZW and have them put tethering on my 6700 (thinking it must be some sort of line kill that they do, only to find out later that the helmi kitchen which i use has that reg tweak that keeps VZW from knowing im teathered.) and still it will connect let me surf for a few minutes or two then it crashs. Any one have any idea whats going on? im going to reflash tonight just to see if that helps.
