Review: Kyocera Koi KX2
Browser
It's hard to love a browser that's locked to a carrier's portal, but the one benefit to the lock down is that it comes pre-configured and there are no setup issues - click Mobile Web from the main menu and you're off and running. Browsing speed is reasonably fast, and there's good feedback to let you know it's working while sending and receiving data. This is a necessity since browsing was unusually slow most of the time. That may be more the fault of Verizon's overly graphic WAP pages than the browser or the network speed.
Customization
The Koi can play both MIDI and mp3 ringtones, however it only comes with a rather disappointing selection of MIDI ringers. In order to put other ringtones on this phone, you'll have to purchase them since BREW allows carriers to lock users out of installing their own ringtones on the phone.
In addition to customizing the main menu appearance, you can customize the color scheme of all the submenus, which are text only. The only other way to change the phone's appearance is with wallpapers. Unfortunately the wallpaper is just a small rectangular graphic on the Home screen, which otherwise retains a white background with icons and text distributed all over. Although the size of the wallpaper is disappointing, it probably improves usability on the crowded screen. Screensavers are also customizable, and will continue to run all the time unless none is selected.
File Management
Media is managed though the Media Gallery application. You can mail and manage pictures, video and audio through the Gallery. Ringtones, wallpaper and certain other files are DRM protected and cannot be sent from the phone. BREW applications are managed from the Get It Now menu.
