Thanks for the suggestion about pulling the battery. I gave it a try and it was no help in restoring the ring tones or alerts.
For the OS version, go to OPTIONS>ABOUT.
Go to Crackberry forums and post this problem on there. Also call 800-922-0204 to Verizon's CS, push prompts to get to tech support and be sure you say BB tech. Also be sure you use another phone to call them on. Did you back up? If so re install back up.
I cannot remember where in the phone you find what OS number you have?
go to options...and about
i didnt know the question was already answered...oops
