Looking for a good Verizon phone for under $100

The features I'm looking for are as follows:

custom, mp3-quality ringtones (files I can make using my computer)

play mp3 files (I'm assuming that lossless formats aren't reasonable/possible)

some means of file-transfer w/ PC's (would prefer not to have to deal with any syncing to Windows Media Player or anything like that)

speakerphone

camera/pictures aren't necessary but would be appreciated

headphone jack would also be appreciated if possible

maybe some sort of countdown stopwatch

I'm pretty oblivious to cellphone features so feel free to adjust my expectations (this will be my first phone). FYI, my family has a basic plan and will most likely be sticking to it, and I don't plan on messing around w/ texting, or any of those pay services. Also, if there's any other criteria that you think I should consider please mention it. Thanks in advance!

If you didn't already get a phone verizon is offering a bunch of phones for under $100 till the end of the weekend.
