My turn at the Sprint wheel of luck... My opening day EVO 4G stopped charging one day, more specifically, only charged when the charging cable was held in a certian position, otherwise no charge.
I saw this thread and tried the closest Sprint corporate store (in Rolling Meadows,IL) where after 45 minutes I was handed my phone, and a reciept with my previously semi-functioning USB port taped to it...
The clerk, asst. mrg and the manager (Jessica) told me I had to place and insurance claim to get a replacement phone. She explained that any damage to the motherboard was considered physical damage and that Insurance was my only recourse. After explaining that this seemed (based on the posts here) to be a mfg defect, and that it didn't seem fair to have to pay the $100 deductible (I carry the full insurance) she gave me the number for HTC to call.
I tried another corporate store, in Addison, where I was told the same thing. I then tried the store closest to my home (Bloomingdale,IL) and was comforted by the mgr Bobby, that after Oct 24, Sprint decided that damaged phones (that were not a total loss) and covered under full insurance would be replaced, still through insurance, but without a deducutible!
He offered an external battery charger to get me by, but apparently the last customer who needed it failed to return it. When all else failed, he gave me a quick charge from another phone and told me the replacement would be in on Monday (today is Friday night).
Bobby explained that his store was NOT a corporate store, and had more incentive to make me a satisfied, possible re-occuring customer. He definitly put the effort into it, and even though I get to go cold turkey for the weekend, which my wife will appreciate, am happy with the resolution at this point.
BTW I am typing this from his store, through their Overdrive mobile hotspot
He took it in the repair depot and managed to get the usb port re-attached, although it doesn't look like it's going to charge anymore.
