well what i used to make them was sonjy soundforge7.0, which is a $300 program, so, if you want to make them find any mp3 editor that allows you to crop the song, so you can make your 10-15 second clip, and then convert it to a wav program. Then go here - http://smaf-yamaha.com/tools/downloads.html - and find this program - WSC-MA2-SMAF. This program will allow you to drag and drop the cropped wav file onto it and it will automatically convert the wav to an mmf file for use on your phone. Now as far as gettin them on your phone you can make a site like i did on tagtag.com , or you can go to www.coolservice.dk/en/compatibilities.php to upload the file online. They will give you an id and on your phone go to wap.coolservice.dk and enter that id given to you to download your ringer. (Works 100% of the time).

Word of advice - don't make the clip too long, otherwise the file will be too big and your phone won't accept the download, as a general rule make the tones as big as 50k, no more, but you can experiment to find what the actual max filesize is, hope this helps, let me know how you do!

You are amazing, thank you so much. I do have a question, though. If I wanted to start making my own and with decent quality, considering ToneThis was quite bad, what would you suggest? Your ringers are brilliant. Thank you so much. This was perfect! ;*

well it doesnt take mp3 ringtones, its actually a different format called mmf, or multimedia format, and this site - tagtag.com/kinjutsu - which is mine, has a bunch of voice ringers that i made back when i still had my samsung phone, the clips are around 10-17 seconds long each depending on the song, considering there is a max filesize for downloading. try going to that site, if you go to the ringtones thread there is a thread stickied to the top called 'My (free) MMF ringtone site" where it has a list of the available tones, with more comin soon

Hi, guys! I am sorry if this has been asked before, but. I just came to T Mobile from Verizon because of how poor Verizon's customer service was: whatever, but the one thing that matters to me is my mp3 ringtones. What can I say, once you go mp3 you cannot go back to polyphonic. The 11 seconds from t-zones is even worse considering they cut off right in the middle and I am pampered and used to 30-45 seconds, mostly where I jam out until I answer my phone. I have the Samsung E-335 or E-336, I forget which, it's a small, dark blue flip phone. I love my t-mobile. I love my services, but I cannot find anywhere on the internet that supports my phone and t-mobile at the same time. If anyone can point me in the right direction on where I can find a site, I'll be forever in your debt. Thank you so much.
