Sadly I have to retract my vote as still having my orig Evo... Over time it started taking longer and longer to boot up, to load pages, videos, anything. Then it started rebooting randomly, then back to back reboots, and after about a week or 2, boot loop cycles. Boot all the way to the home screen (taking 3-5 minutes) and reset, over and over till Id pull the battery. Pulled the SD card, and reloaded several times, cleared the cache, or whatev through the boot loader menu, everything. After taking it to BB (where I got it) they told me it would take 2+ weeks turn around, and the loaner didnt have GPS (which I NEED for work) so that was a no go, went to a Sprint service center, and the tech was certain my internal memory was failing/corrupt. Same thing the guy at BB said.
Anyways, even though I have BB insurance, Sprint said they understood I need my GPS for work, and for $35 had another phone there ready and waiting for me by NOON the NEXT day. +1 Sprint, that saved my week. It WAS a refurb, but, had only like 200 lifetime calls on it, which is a small fraction of what I had. It boots in under 60 seconds or so, and the sound quality seems to be alot better, speaker phone and earpiece. It was a 03 ver I had since June. Was a hardware defect for sure, not user error. Still totally happy with my phone, and REALLY happy with Sprints customer service even though I didnt have their insurance, or even buy the phone through them!
