Generally I do shopping from ebay but one of my friend suggest me other portal to buy mobile phones, I buy my last mobile nokia c3 from them and the service provided to me was admire. During searching for lattest upcoming mobile phones I read about some interesting mobile phones Motorola Atrix(dual-core 1GHz ARM Cortex-A9 processor) and Samsung Galaxy S2(thinnest mobile phone in the world). And If you are crazy about gaming there is good news for all gamer like me Sony Ericsson Xperia Play (worlds First Playstation certified Android smart phone) is coming almost in next month in UK. I am so exited to have reviews for these mobile phones.
I buy a lot of stuff on e-bay, but not electronic gadgets. I prefer to test the items myself and I just don't think it's worth the hassle of shipment, returns, etc and risk of being scammed. But if you plan on selling something online, obvious choices are eBay & Craiglist
I just read about this envirofone website. They recycle old mobiles, so that could be a little help to the environment too. or else you can check with mobilephonexchange too. For buying still I would recommend some comparison shopping sites for lowest price and best quality match. Try recombu for comparison.
The model of Samsung Galaxy S2 is I9100, which is the developed model of Galaxy S I900. Galaxy S2 continues the classic appearance of Galaxy S and the design is more angular. Ultra-thin design is also a major part of this phone. It’s well-known that Sony Ericsson Xperia Arc wins the world’s thinnest smart phone with 8.7mm in CES 2011. However, this record will be changed by Samsung Galaxy S2, which is only 8.49mm. Therefore, Samsung Galaxy S2 now is the thinnest mobile phone in the world.
Samsung itself revealed some details, and one of them is that Galaxy S2 will have “Retina†screen – it’s the second “Retina†after iPhone 4.According to Samsung, Galaxy S2 will have Super AMOLED Plus display, which is even brighter than Super AMOLED screen and it also has a regular RGB matrix instead of “Pentile†matrix, which was used in Galaxy S. Also S2 is going to have screen resolution with over 300 ppi (pixels per inch) and that means it can be called as “Retina†– when human’s eye is unable to see separate pixels.
There are many online markets for mobile phones like ebay, gumtree etc. Google is your friend, search.
