their own problems. I've used both Verizon and Sprint until I completely switched to Sprint. Verizon had excellent call quality, but their plans were more expensive, and the phones I used would roam in less urban areas. Sprint has some excellent coverage. You can't argue that. Call quality depends on the phone and the coverage, so if your phone doesn't work right, then it's the phone.
I will say that in the last year, I've gone through six (6!!!) phones with Sprint. I originally had the great Samsung A900 which was really good. However, the first one I had was buggy because Samsung messed something up. The second one was also defective and would freeze up and show 3 hour calls when I never made one. The third one was perfect except for one annoying detail: the backlight didn't work. It was impossible to see it outside and inside. The software wroked fine, but this time, it was the device itself. I was really mad at the Sprint customer service (they are/were horrible), since they couldn't do anything to fix it. They didn't even try. I decided to get a KRZR when it came out in hopes of having better luck. First one: freezing, buggy, etc. Second: battery would screw up, phone would turn on and off, restart like a computer. Third one: the one I have now.
That's my speel about Sprint, but their coverage is excellent and what's more is I have better reception where the A900 did not. Dropped calls: I have had quite a few, but that was due to my friend's Q, which wsa buggy, and had some serious issues. Never have I dropped a call on MY line. Verizon has some good stuff, but they lock their phones down with that horrible software unlike Sprint's. At least Sprint has some more variety. Each carrier is different, so you can't say one is COMPLETELY better than the other. They all have their own ups and downs.
You know, I may try to get one of those new RAZR2 things. Looks good on Sprint, and the review here on CNET says it was great. Promising I hope LOL.
