LG :: Flare Virgin Mobile / Bluetooth Lockdown / Custom Ringtones

I just bought an LG Flare from Virgin Mobile, and I have the $25 month plan with unlimited text + web. My goal is to have custom ringtones in the phone.Here's what I've done so far:I went to www.ventones.com and created a free ringtone, and had them send it as a text to my phone, but that text never came.Ventones also gave me a weblink I could point my phone to. So I did that, but upon getting there my phone says "HTTP Error 406: Not Accepted".Now this got me thinking that maybe MP3 files were not supported. But it says on the box that you can have "real music ringtones" (although any format specification is carefully avoided), so maybe I can have music files, just not as plain downloads (must go straight to system ringtone folder).Then I downloaded BitPim. I don't have USB data cable for this yet, but I'm thinking of getting a $3 one from eBay. Meanwhile, I tried connecting it via bluetooth. Now, reports say that the LG Flare was manufactured with built in support for a number of Bluetooth Profiles, including SPP. However, my LG Flare has only HSP and HFP (with only HFP being recognized in Windows, and both HSP and HFP being recognized under Ubuntu).

So naturally I'm thinking that Virgin Mobile has somehow locked down the Bluetooth. While my primary goal is to get custom ringtones, this restriction intrigues me, and I'll be glad if anyone could help me either way. Because the bluetooth is locked down, it is also possible that the data cable won't help any. What I'm looking for are some unlocking mechanisms which can free this restriction. The phone has 8mb of memory! And I want to use it.
