The release of Apple`s iPhone spearheaded innovations by other mobile phone manufacturers. But the sales of iPhone surpassed them all. Apple subsequently released the iPhone3G.
If you are one of those who couldn't buy the Apple iPhone or the 3G version (and are still secretly craving for one), grab a refurbished piece. It still holds the warranty as the original iPhone. The refurbished iPhone is like any open-box item you find in stores. The originally owned piece is repaired, tested, and brought to the market with the original warranty, only this time at a low markdown price.
If you can overlook a scratch, I say, go for it! Moreover, it comes with a one-month trial or money back policy. If you are unhappy with your iPhone 3g, just return it within the stipulated time period. Additionally, almost any cell accessories site on the internet will have iPhone and iTouch accessories.
