Tethering does not appear to be an option, nor is operating the phone as a Wi-Fi hotspot.
The Infuse comes loaded with Android 2.2 (Froyo). As with other smartphones, it comes with the customary bloatware, which in this case is pretty unobtrusive: a media hub app for downloading movies, a Yellow Pages app, an AT&T navigation app, an app that wirelessly shares videos on your phone with other devices and a special custom version of Angry Birds.
At a Glance
Price: $200 with a two-year contract and data plan
Pros: Big bright screen, comparatively light weight, 4G network
Cons: Uses AT&T's quirky network
You can choose from among no fewer than three virtual keyboards: the Android standard, Samsung's keyboard (which offer predictive text and some layout differences) and Swype.
There's a nice interface touch in the Infuse's Contacts database. You can swipe right to call a contact and swipe left to text it. It's clever and convenient.
When you do call, the phone sounds fine. I didn't have a chance to use the phone for more than a few hours, but judging from my experience, the battery will likely last you a full day and a little more if you don't go crazy with apps.
In short, the Infuse is a lightweight only in the physical sense. On Verizon, this would be a killer phone. On AT&T, it's merely very, very good.
