ok i have tried every site for my server and have found no help. the only tones I can custumize are my ringtones. All the other tones for text and e mail ect ect only allow me to use the default tones the phone came with. NOT EVEN CUSTOMER SERVICE COULD HELP ME WITH ADDING MY DOWNLOADED TONES TO MY TEXT MESSAGE ALERTS. this is a basic feature that it seems this advanced phone didnt come with. my old fossil of a phone allowed it. help anyone?

Most smartpone only recognise wav formats as text alerts... wat u can do is convert ur mp3's to wav format n place the tone under ur fone windows folder. this is the only alternative im using.

I found a step-by-step guide that I used to solve this problem for myself:
ok, so after some playing around with the regisrtry of this phone I found a hack that you can use to sole this problem, of course you are going to have to find a registry editor for a windows mobile phone.

ok open a mobile registry editor, open HKEY_CURRENT_USER

open CONTROLPANEL

click on Sounds

change the file size limit to 999999999

and change Ringtones mulitstring just to Ring-WindowsMobile.wma (delete all other ringtones listed)

open Sounds and click on RingTone0

change savedsound to \My Documents\My Ringtones\*the song you want.mp3*
with out the *s
make shure that song is in your ring tone folder

change Sound to the same thing as savedsound

restart your phone, and you should be good, all the songs in your ringtone folder should now show up in settings>sounds>Ring tone:

hurray now you are done, please do not take credit for this hack, give credit where credit is due

** i am not responsible if you mess up your phone by doing this hack, its your fault, because it worked like a charm for me**

=========================

This worked perfect for me and should for you if you follow the steps.

How do you set you duo to play a ringtone larger than about 150 kbs?
