where can i find one? my friend has a sidekick 08 that she is willing to sell for my son, but she said the battery doesnt hold a charge..i dont know if it is a phone issue or just the battery..i seen a few on ebay for under 10 bucks but i have never purchased after market batteries before

and does anyone know how that would be added to a family plan..right now i have a individual plan even more plus behold 2..woould have have to have 2 data plans?
