Is GSM to blame here, or something else? I'll admit, I'm not really a fan of GSM networks around here - have had several people's calls just drop for no apparent reason when they're using GSM phones; T-Mobile or AT&T. Even worse when on the edge of coverage, it seems far less reliable than CDMA, especially in "fringe" areas.
Never had an issue w/my CDMA phone, even at large events like Lollapalooza last year (sponsored by AT&T) - granted, Chicago is also 'home turf' to my carrier, U.S. Cellular  |

Mount Airy, MD | Wasn't AT&T's 3G network some sort of hack of CDMA?

Hack is a bit of a bad term for it.
CDMA is a spec for an air interface, as is TDMA and AMPS (analog)
CDMA2000(CDMA 1x/EVDO) use a 1.25MHz carrier channel and ANSI core (compatible with AMPS/TMDA)
UMTS/WCDMA uses a 5MHz carrier channel and MAP core (compatible with GSM)
UMTS/WCDMA is closer to EVDV, as it runs both voice and data over the 3G network.
With CDMA 2000, voice goes over 1x, data uses EVDO or 1x.
The main issue with UMTS/WCDMA is the size of the 3g voice/data channels. 5MHz is 'huge' (ie. 1 carrier hannel is the equivalent of PCS D license block) This poses problems for migration of users to 3G where spectrum is tight. Here in L.A., where 1 carrier channel was initially deployed, 3G was unusable for voice/data as it was typically overwhelmed.
In the end... AT&T just dropped the ball. |

Problems I see:
1. Too many iPhone users.
2. Apple's love with "we only do it."
3. GSM networks are just plain overloaded.
4. Coverage sucks. (Non-GSM is just plain better. Bagphones are analog and had better signals).
5. Putting too much crap on a phone. Do you have a MP3 player, Camera, Internet browser, etc. on your home phone? No.
6. Made in China. (I would never buy a DVD or VCR player/recorder that said "Made in China")
The Most Important Reason:
7. 1 T1 line supplies a cell tower. (Sorta like using a regular pipe in the home to flush 50 toilets at once. That doesn't work either.) |

Only ignorant people would blame GSM when it's the network standard for the biggest and most advanced wireless networks all over the world.
No it's NOT GSM - it's the GREEDY, PoS incompetent AT&T, nothing else.
