The slim i425 cell phone, made by Motorola for Boost Mobile, uses iDEN technology (integrated digital enhanced network, multiple communication devices all-in-one) and can thus make the claim of being the slimmest walkie-talkie phone ever made. Less than half an inch thick, it's also very light (just 3.9 ounces) and is the first Boost mobile phone to have environmentally friendly packaging (whatever that is). This i425 has wireless Web, text and multimedia messaging, AOL, Yahoo and MSN instant messaging. Wait, there's more — there are Java-enabled games and applications, voice-activated dialing, GPS and of course ringtones.
Did I mention that almost every single one of those extra features costs money? With the Boost network you either pay separately or buy bundled packages. The i425 cost $60 and comes with a $5 call credit. It hits the streets it this September with either a white or "espresso" shell.
