need help with my nexus s problems

[roguefromnyc]

What's up ac forums.had a couple of concerns with my phone. my nexus s stock running 2.3.2 rooted and unlocked. Here are some of my issues so far
While driving and on the phone, sometimes the call drops after making a nasty sound and stays stuck on the hanging up screen and I can't make or receive a call till I reboot.
When turning the phone off sometimes and turning back on, the screen hangs for a while and 4 seconds later ill feel the phone vibrate 2-3 times and go back to normal in which its not lagging.
When opening my gallery the phone takes about 5 seconds to show me my thumbnails of my photos.it does this every time. Also when I take pictures it takes about 10 seconds to see the photo I took. When talking on the phone I drop alot of.calls or I hear the person sound like a chipmunk lol.
Is my phone messed up? Is the stock rom messed up? I flashed a stock image thru clockwork after I tried a alpha cm7build. Was it corrupted or is my phone a pos. My nexus one never gave me this many problems.
Any help would be great

It could possibly be the ROM you flashed.
