Okay, I am the ULTIMATE try before you buy person. I will usually fetch a serial off the net and give a program a REAL try before spending my dollars on it. 99.9% of the time, said program is uninstalled within hours because it's a piece of ****. This one is worth the money! I had a slight issue in that my confirmation email didn't contain my serial, not did my receipt page. I sent an email to Efiko with my receipt #, and they got back to me within a day with my serial. A few things I have 10 ringtones up and running. A few tips:
1) Audacity (or something similar)... I had a few problems with ringtones not playing after using iPhoneRingToneMaker (iPRTM) to edit them. I have had ZERO problems when using Audacity to cut, fade, etc, then creating the ringtone with iPRTM.
2) Save your edited MP3s somewhere OTHER than your iTunes\Ringtones directory. I had a couple that would not play when I was saving them there.
3) The "-1" error is NOT associated with iTunes. I've never had iTunes open while using iPRTM. I think it has something to do with the "state" of your phone. Once, I got it while my phone was locked. Another time, I was still in the ringtones list in my phone. It doesn't seem to like that
Bottom line: I use Audacity to trim the MP3, save it in My Documents\Ringtones, then go into iPRTM and create the tone. So far I have uploaded 10 in a row that all worked on the first shot. Great piece of software, well worth the $$. I'm not a hacker, but if anyone has any questions, feel free to ask and I will do what I can to help.
Yeah cobrita, you might be on to something there.... As I said in my post above, I use Audacity to make the ringtone sound how I want, then just hit the "create ringtone" button. But now that you mention it, I was showing someone how you could save a step and do this in iPhoneRingToneMaker last night, and I DID preview it, and it gave me the "-1" Nice find!
