I'm saying the service and design both suck. I have yet to use the i95cl or the other new color one i733, but my i90, i58sr, and i80s have all performed real bad for one reason or another. The service seems to blow in general even though we are in an area that supposedly has great coverage (Cleveland). Like Lounatik said, it is always "what..what did you say" or "say again", etc. I always get "call failed" or a very long pause when I dial and then it will ring, or the voice gets all broken up. The walkie talky feature is even more retarded...."cannot find user", yet they are in the room next door, etc.. and it is really annoying if you don't hit the PTT button just right or you get that dang long beep where you have to wait 10 seconds before you can try again.
The i90 was the first phone I had. The battery blew, as did all the dam volume settings. I would not even use the phone and it woul need charged after a few hours, this was even after I tuned all the battery draining options down. Sometime the phone would ring real loud other times I wouldn't hear the alarm go off because it was to low. Figuring out the multiple differnet soudn settings was a pain. And to boot the phone would just turn off by itself all of the time.
I did like how it was somewhat compact, but comared to other phones it is still gigantic. The durability seems rugged to as it eventually was beat pretty good. This was after it never worked in the place so it getting beat up had nothing to do with its performance. I had three different i90s.
Next I got an i80. This thing is about a foot long and could probably be used to knife someone? It didn't really fit in any pockets etc, and was easily scratched up. The service did all the same crap as the the i90. The worse part was how it would shut off when you went to talk. Apparently the battery case would flex just right when you put it up to your ear so it gave the battery just enough room to loose contact and cut off. It was weird becasue it didn't do it right away, but after like a month or so. The whole fleet of phones started doing it too. You could fix it by wedging some paper in there but come on?
The I got the "rugged" i58sr. This thing comes with a super battery that supposedly has a super long talk time. Funny, I don't use it and it is dead by the end of the day? he super battery and phone weigh in at about 15 pounds and the phone is about 1" thick by 4.5" long. Try storing that anywhere. If the battery isn't dead and I do get to talk for more than a few minutes my arm is dead tired. But this thing is super rugged and can take a real beating, and doubles as a workout device.
If I didn't have to use these for work I would never ever touch a nother nextel phone. Their account reps suck, the service sucks, and the phones cons out weight the pros in each of my cases. The reallly good thing is the speaker phone option whihc is really loud and clear, but only when you are actually have a clear connection to teh other person and the phone isn't dead, cutting off by its self or acting up.
