Kim Kardashian has just recently put her new T-Mobile Sidekick LX up for auction on eBay. The phone is apparently one that she never used so she decided to put it up for auction and give a percentage of the sale to charity. The phone is only at $173 right now so its pretty cheap for a new Sidekick LX, plus its signed by Kim Kardashian. So if you are looking for a new phone or are a fan of Kim’s this might be worth checking out.
