I have had the Rhyme for a few days. I like it, but it seems like it doesn't check for new email, although I have it set to push. All the settings seem to be in place but I don't see new emails appear until I manually refresh the inbox.
I had sync turned off, but background data on. When I turned it back on, it worked. I thought sync meant something else, like sync with a computer.
I like the phone. The music player is good. I use my library's Freegal service to download songs onto it.
