Anyone have any info/experiences with the Samsung 390g? Walmart has them (Net10) for $50 right now. Not much info on the web, so thought I'd try my luck here. I love my LG900G, but wi-fi is tempting, plus the phone works on the $25/750min monthly plan. The box says "3G", but I assume I'd be limited to EDGE while using on Net10. Any comments would be appreciated!
