Took mine to a sprint store today, started having charging issues last night. They are shipping me a new one free, but the tech said that it did look like damage and not a manufacturer's defect. Personally, if you are using a product normally and it breaks, that may not be a defect in materials, but it is a defect in engineering and design - which is part of the manufacturing process.
It helped that I also brought my daughter with me and signed her up for an Epic on our family plan.
My evo will only charge now if contorting the cable - if it's laid down slack, no charge.
To combat this I'm buying an external charger, so all I need to do is pop a battery in my phone in the morning, and if the tales are true of the 3500mah batteries, I should be able to make it all day without needing a charge
USB ports are for ROOTING not for CHARGING!
Sprint's customer loyalty program is their network... Not nearly enough to do the job
