Speaking of my Pre, I had been having some problems with it lately - it thought that headphones were plugged in to the headphone jack all the time, and so I couldn't listen to music or use the phone except on speakerphone, which got annoying pretty quickly. I tried some internet-suggested remedies that worked for a little while, but this weekend even those stopped working, so I took it in to Sprint to see what they could do.
I dropped my phone off at the nearest Sprint service center, got lunch and returned to have them tell me I'd be shipped a new phone and it would probably arrive the next day. And they let me keep my phone in the meantime (and ship it back when the new phone arrived). Lo and behold, yesterday it arrived, today I took it in to be activated, and it seems to work like a charm. After being careful not to nuke my existing backup (not actually sure if this is a problem anymore, but better safe than sorry!), it transferred over my contacts, apps I had installed, and even bookmarks! So +1 for Palm and Sprint for taking care of the problem.
