I don't see why you would lose your unlimited data. If you purchases the phone and keep the same plan, everything should stay the same. BTW, I just purchased the Aria and am anxious to get it. I have done lots of research and it appears that most Aria owners are very happy with the phone.

 

1. Just copy and paste your music files to the SD card. I copied/pasted an itunes (AAC) files just to see if it would work, and it does. It automatically converts it to a m4a file. (I have a windows PC btw, not sure if that matters)
2. Copy n' paste
3. not sure about tethering
4. You can use AOL accounts. I believe you can use any type of account for that matter.

 

I believe it has it, but it's a service you have to pay for from at&t. If you root the phone, you can get free tethering. I have a custom froyo Rom (based on the HTC gratia Rom) and it includes WiFi hotspot, which I assume is the same as tethering (please correct me if i'm wrong.)

I've had the aria since the first week of release and I am really satisfied with it. Best phone I have ever had.

 

On my Aria you can tether Internet, just plug in the USB and it gives you some options like Mount Disk Drive, Charge Only or Share Internet.

 

The Aria is my first smartphone, which I've had for two months, and I'm not a heavy user. I use it as a tool for work, primarily for email, some useful apps, the GPS occasionally. I wanted to have one device that would have the above along with my music, pictures, and documents for work. I use the native web browser which is very speedy.

Since I have nothing to compare it to, my opinion of the Aria is very high. I like the size and overall it is just very responsive and reliable. Luckily I don't use my phone to text or send many emails. My only problem with it is the small screen, but only becasue I fat-finger the keys a lot when I do use it for a search or a brief message. Otherwise it's perfectly OK.

I don't think HTC has provided sync for MAC yet. It does appear that there are third party sources that will allow you to sync to your computer.

I agree with a previous post, especially since the Aria comes with only a 2gb SD card. I got a 16gb card and a reader and put all of the music, pics, and other information I wanted on the card and then installed it in the phone.

I think the Android 2.2, which is rumored to be coming soon, allows tethering, although again, I think there are other means to do this, probably free. A little research will confirm this.

I have had an Earthlink account for years which I don't want to give up. Once I had my phone, I created a gmail account and I forward everything from my Earthlink account right to the gmail and then to my phone. Very simple and it also provides a great place to archive.
