Sara really loved her HTC G1 from T-Mobile, and bought the similar-ish Samsung Sidekick 4G as a replacement when its years of loyal service ended. The new phone has not been so loyal. It locks up, won’t respond to the touchscreen, and periodically wipes its memory card for no clear reason. Sure, she could back up the memory card content elsewhere, but the non-operational phone is a real problem. Now she’s on her third replacement. T-Mobile is happy to send her a replacement, but she doesn’t want a fifth phone that will inevitably have the same problems. Sara, welcome to smartphone replacement purgatory!
