Let me say off the bat that I had been REALLY looking forward to getting this phone. I saw a great deal on Amazon and ordered it. However, when I tried to activate the phone it was listed in Sprint's database as a stolen phone! Obviously I sent the phone back to Amazon (along with a curt note!) and then bought one directly from Sprint. I loved it from the moment I took it out of the box... very slim, sleek, and sexy. I spent many, many hours setting up the phone just how I wanted it, including pictures, ring tones, and display preferences. I should have waited until I'd made sure the phone worked.Within a few uses I knew there were problems. Major ones. Over the course of two days I had the phone shut itself off and reboot randomly four times, display the incorrect caller ID and use the wrong ringtone for contacts, have the ringtones sounds like music played on an underwater stereo, and have the picture display show up like an old TV set with bad "rabbit ears" (remember those fuzzy, squiggly lines that would appear all over the screen if it wasn't a good signal?). I called Sprint and told them what I was experiencing. They said they hadn't heard of those complaints but would be glad to exchange it for me FOR $55 SINCE I DIDN'T HAVE A REPAIR CONTRACT WITH THEM! After I pointed out how ludicrus that was - charging me to swap a phone that was defective to begin with - they sent me another one free of charge. I was much smarter with the second phone and didn't program anything until I made sure it was working. Guess what? It had the SAME problems. Now I knew it wasn't just a fluke that my old one acted up. I then went to the Net and did some research, and it turns out that many, many people are experiencing the same problems I was (and yet Sprint still says they aren't hearing of these issues, which I find hard to believe). I once again called Sprint and had them send me out a 3rd phone. There was a 2 week gap between ordering and receipt and while I was mad at first that I was stuck for a while with a defective phone, it turned out to be a good thing bacause it allowed me to receive a phone from a new "lot".My 3rd A900 hasn't rebooted and hasn't played the incorrect ringtones. I was able to get around the scrambled-looking picture ID's with a tip I'd read from others who had experienced the problem. It occurs on long-distance numbers and apparently putting the "1" before the area code confuses the phone; if you remove it then the phone (and picture) works fine. I've now had the new phone for two weeks and think I'll keep it. I had already invested over $100 in accessories before I found out my first one didn't work so I am very hesitant to switch to a new phone (although Sprint offered to swap it out for a different - less expensive! - phone "at no charge"). I'm going to be downloading my own ringers on to it later today and hope that it doesn't mess up the good thing I've finally got going.In short, if I had to buy this phone again I wouldn't. It's obvious that there are still many bugs and problems with the software and no solutions on the horizon. It seems to be the luck of the draw whether you get a phone that works as it should.
