I have a unlock and jail broken iphone that was on 1.0.2 and I recently upgraded and then unlocked 1.1.1, Then used jailbrakme.com to unlock and jailbreak
However now when I use I bricker version 9. I can upload and convert mp3's but I cannie see them in teh sounds section for the ringtones.
Thats because v1.1.1 and 1.1.2 use the new controlled method of only allowing iTunes based RingTones.
You can get around this by applying the MeCCA patch for 1.1.1, its just a MeCCA file that you overwrite and it makes the Ringtones folder back to normal again, search for that file in the downloads and apply it, and you will be back to your original Ringtone setup.
Have you installed SSH on your iPhone? If so have you turned it on (if you turned it off via Services or iToggle) ?
If not you need to install OpenSSH from Installer or possibly through iDemocracy. Everything is done through SSH. Only apps like iBrickr, iPhonelist, iPhonebrowser actually connect through a serial link, not through wifi. Thats why I mentioned get the MeCCA file in the right place, then just use the normal apps to get the files in the Ringtones folder if thats what you are familiar with.
Just use iTunes to convert your mp3 to aac (right click - convert to aac), then rename to .m4r
Double click and they will be added to your ringtone list in iTunes, then sync.
