The Nokia 6265i or perhaps almost all Nokias can be unlocked so you can set your own ringtone. All you need is a USB cable CA53 or any compatible ones, bluetooth will never work, you also need a program called Diego, Nokia PC Suite also will never work neither.
Upto now as I know you won't find that USB cable at anyTelus stores, the best place is eBay for dirt cheap money. once you installed Diego, hook up the 6265i then wait for Diego found the phone, you can go ahead tell Diego read all from the phone, if you worry because you don't have confident in hacking then you should back up the phone configuration first, this can be done with Nokia PC suite. Now browse through the left folder in Diego near to middle of the page you will see User setting > Ringtone, open it up, on the right panel a blue highline showing ringtone setting at #2, click the arrow change it back to #0, then click write all to the phone, wait for the phone reboot, unplug the cable. You're done the job, the entire work will take less than 5 minutes, do not pay someone 50 bucks to unlock it, yes you can do it, I did it for fun but I still like some default ringtones from Telus.
To create yourself ringtones, you better have Audacity (free d/l) and Razorlame (also free). Audacity let you edit, adds special effect and trim your sound clip then Razorlame can encode back to MP3. The length of ringtone going to use should not longer than 20 seconds.
Hope this can help, because I like every ones in this forum, after reading many reviews about the phone, get out and bought one just to find out that it was handicapped by Telus. I am never a pro but internet is the place to search for, by the way did you know that Baidu.com is right now in head to head with Google in Asian countries ? If you can't find overhere then you will found overthere.
Have fun.:
