I had my eye on this phone for quite some time, so once I heard Best Buy was carrying it, I ran to the store and purchased it this past October for $399 w/ 1 year contract extension. The phone had the famous low volume problem, which made the phone useless unless using the speakerphone or headset. Cingular/Motorola supposedly fixed the problem, and released the phone again with an updated firmware (the boxes were marked with an orange sticker). After Best Buy replaced my phone, I was very sad to find the updated model had even more problems! The volume is still VERY low and not fixed, and a number of additional bugs have been introduced. The most publicized problem being the Bluetooth headset problem. I eventually took the phone back, after a long battle with Best Buy and was given a store credit (now I'm stuck with an extended contract, and I could not get my replacement plan fees refunded).I am not the only one with this problem. If you do a Google search using the keywords: MPX220, VOLUME PROBLEM, FIRMWARE, BLUETOOTH HEADSET PROBLEM... You will see NUMEROUS postings and reviews with the same complaints. Sad thing is Motorola tech support is not acknowledging the problem, nor is Cingular.This entire experience made me a Motorola hater... This is very sad, because the phone does have some great features. The Quad-Band feature is great, and ensures you'll have reception all over the world. The Microsoft Smartphone software is AMAZING, and it was a joy not having to carry my PDA. Windows Media player is nice, and the expansion slot allows you to use the device as an MP3 player, camera, video recorder, etc. I would have to say this is one of the best Phone/PDA combos I have seen. Unfortunately, the volume problem makes the phone useless... And the numerous software bugs are impossible to overlook.My advice, wait until January/February before giving this phone a try... If Cingular is still selling it, it probably means they fixed the problems. I doubt they will keep selling a defected unit that long, so if it is not resolved by then, they would probably stop selling it.Most importantly, do your research on the net, and read what others have been saying. If the phone is improved, it will reflect in the buyers comments.Hope this helps!
