You can find more apps in the Android Market, but unfortunately, you won't be able to download any non-Market apps to the phone. As it did with the Motorola Backflip, AT&T removed the Unknown sources option in the Applications settings menu that would let you install third-party apps, such as Swype Beta for Android--an app that would be incredibly handy on the Aria. This limitation is incredibly annoying, especially when other carriers don't put the same restrictions on their Android phones.
The Aria's phone features include quad-band world roaming, a speakerphone, speed dial, smart dialing, voice commands, conference calling, and text and multimedia messaging. The phone also has Bluetooth 2.1 with support for stereo Bluetooth, but as a limitation of Android 2.1, you can't voice dial over Bluetooth.
The Aria is a 3G device and also has integrated Wi-Fi. It comes with Android's WebKit HTML Web browser, which is quite capable in functionality and performance. It supports multiple windows, Adobe Flash Lite, and it includes the recent feature where you can look up words and phrases in the dictionary or Wikipedia by performing a long-press over some text on a Web site. You can also select a whole paragraph to send to Google Translate.
With the phone, you can stream multimedia content over 3G and Wi-Fi. Like other Android devices, the Aria comes with a dedicated YouTube player as well as a built-in music and video player. HTC Sense does a good job of making the music player's interface more attractive compared with the stock Android player. It supports a number of file types, including MP3, WAV, WMA, AAC, OGG, WMV, MP4, and 3GP, among others. It also has an FM radio.
The Aria's 5-megapixel camera has a good range of options, including settings for brightness, contrast, saturation, ISO, and effects. However, it doesn't have a flash, so the quality of photos taken indoors is a bit degraded with a duller, dreary effect. The Aria's video quality wasn't bad, though its picture could get a bit blurry during action sequences.
We tested the quad-band (GSM 850/900/1,800/1,900MHz) HTC Aria in New York using AT&T and its call quality was mostly good. Calls made with the sounded slightly harsh on our side of the conversation and had the occasional background hiss. We were still able to continue with our conversations, but the experience certainly could have been better. Meanwhile, our callers raved about the audio quality on their end, noting the crispness of calls right away. Its speakerphone quality was quite decent with ample volume, and we had no problems pairing the phone with the Logitech Mobile Traveller Bluetooth headset or the Motorola S9 Active Bluetooth headphones.
AT&T's network provided us with reliable 3G coverage throughout Manhattan, with decent speeds. CNET's full Web site loaded 21 seconds, while CNN's and ESPN's mobile sites loaded in 9 seconds and 10 seconds respectively. With Adobe Flash Lite support, YouTube clips played back with no problem from the Aria's Web browser. It took just a few seconds to load over 3G with continuous playback, but the quality was pretty murky. We had a similar experience when watching MobiTV clips. Our own MP4 videos played back beautifully with synchronized audio and picture, and thanks to the 3.5mm headphone jack, we were able to plug in our Bose On-Ear headphones and listen to songs in comfort and with good sound quality.
The Aria is equipped with a 600MHz Qualcomm MSM 7227 processor, and the smartphone ran like a well-oiled machine during our testing period. It might not have the speed of the Droid Incredible has, but the device was responsive with minimal lag.
The HTC Aria ships with a 1,300mAh lithium ion battery that has a rated talk time of 6 hours and up to 15.5 days of standby time. The smartphone gave us 6 hours of continuous talk time in our battery drain tests. Anecdotally, with moderate use and from a full charge, the Aria's battery barely made it through a workday, so we'll be keeping an eye on that as we continue with our tests. According to FCC radiation tests, the Aria has a digital SAR rating of 0.95-watt per kilogram and has a Hearing Aid Compatibility Rating of M3/T3.
