Okay, so finally I settled down on the Samsung B2100. This phone is known as Marine in India, and Xplorer elsewhere, and claims to be shock-proof, water-proof, dust-proof, and all the toughness it can pack.
So last night I dropped it in a bucket of water and tried to call that number. Bingo, it rang. After about a minute I pulled it out, and wiped it dry. It was perfect. My daughter then banged it on the floor from a height of about 2 feet, and nothing happened. Seems like it is rugged as Samsung claims. Hopefully it lasts longer too. Review in the next post, as I get more familiar with it.
I also see that they have introduced the first solar-chargeable cell-phone (Solar Guru), which has solar-panels on its back. A sunlight charge of 1 hr. gives an approx. talktime of 5-10 minutes, which is not bad especially for those areas that have power-cuts these days. It may click well in the rural zones of India. Apart from that, solar-power is the way to go, and cheers to Samsung for being the first to launch it in India.
