I have used the 4400 since its launch and continue to sell it to my customers. If I can offer yet another angle... When comparing the 4400 to the 720, I can say that from a warantee standpoint, the 720 is consistently sent back for repair and replacement whereas the 4400 is hardly ever sent out. Granted the improvements are vast in reguards to the newer 730 model, I am also sceptical. Go with the 4400, bro.
P.S. Be aware upon buying it that you have the software version in the phone is up-to-date. there was recently a batch of phones released with outdated software requireing them to be 'flashed' with the new version. the version # should read :TC4VZV08 and can be found under Phone Info.
Well, let's compare... Both phones have basically the same features except that the 8600 has a built-in speaker phone. Thats all well and good, but what are you looking for in a phone? The 8600 is alot more narrow and feminine-looking. When I hold one, I'm always afraid I'm gonna break it. Dainty! I tend to stay away from audiovox because of their customer service. They arent willing to cover anything under their warantees and my customers seem to get better reception from an LG phone.
I would like a speaker phone but it is not necessary. I like the way the VX6000 feels but I don't need the camera. In all I want a phone with the best reception Audiovox 8600 or LG VX6000? Is the VX4600 coming out anytime soon? I see that it has a speakerphone too.
