This website will allow you to upload any mp3 (or other digitally formatted music from your computer) directly to their website. It has an editing tool that allows you to select the start and stop positions of the clip, and then allows you to email it directly to your phone or save it to your computer. The file size limit that can be transmitted as an attachment to your phone as a text message is 500kb which is roughly 30 seconds recorded at 128kb/s.
Once you receive the text message and the clip starts playing, just hit options and select save as ringtone. This will save it into the hidden ringtones folder on the phone and you're good to go.
Bitpim is a free application that can be downloaded to your computer that allows you to fully access your Verizin phones file structure. Aside from being able to make ringtones, you can download your contacts, messages, calendar, etc... edit them and put them back on the phone, as well as edit the param table in the phone to hack DUN and WAP settings. Bitpim allows you to connect via USB cable or through bluetooth (if your phone allows it). This program only works on CDMA phones.
Bitpim doesn't work yet with some of the brand new verizon phones and we are patiently waiting for an update. Check their website or http://www.howrdforums.com for compatibility.
If you have your own sound editing software to make mp3 clips to use as ringtones, just edit them as described above and then email the clip as an attachment to firstname.lastname@example.org.
If you have questions just ask, and I'll do my best to answer them. I may not be able to help with technical phone specific questions, but I can probably point you in the right direction.
Stop paying for ringtones and make your own, better ones. Post up what you've made! :mrgreen:
