This is too funny because I was about to post a thread asking the same question...
Well the information I have gathered is:
After googling around I found 2 threads that have given me a little more information at least.
First is this:
http://pdaphonehome.com/forums/ppc-6...tml#post632387
This explains that there is an Extended Rom that I believe includes these .cab files
- AudioPara0330.sa.cab
- DefaultRingtone.sa.cab
- GetGL.cab (Goodlink, not necessary for most people)
- GroveMobile_plugIn.sa.cab (I think this is for the Sprint Music Store app)
- MoveLnk.sacab
- MP_CVSDcpl_20070129.cab
So GroveMobile_plugIn.sa.cab looks like the one!
Next I found this:
http://forum.ppcgeeks.com/showthread.php?t=5204
Which has the .zip file called:
titan_extrom_tools_179.zip
I tried installing the .cab file inside of the .zip file and it installs a program called "BlueFrog Ext_Tools"
I then go into file explorer and I do have a folder called ExtRom_Tools in my programs folder but there is just a file called "Titan_ext_rom_unlock" and when I click it I get a box that pops up and says "SUCCESS"...
Then after a soft reset I go back to file explorer and now see a folder called "Extended_ROM" in the My Device directory. Inside the folder are all of those .cab files listed above. I tried installed the GroveMobile_plugIn.sa.cab and I can either install it to the Device, Extended ROM (a new option that I haven't seen before) or Storage Card. I tried Device first, which worked and I now have the Music icon on my today screen but I get an error when trying to open it telling me that it's not signed or something and it won't open. Then I go back and try to install it to Extended ROM and it just fails the intallation.
I haven't tried installing any of the other .cab files from this but I'll be glad to post more info as I go along... gonna try a couple more things.
Hope this info helps! I'm dying for my music store back.
Also, I'm using VetVito's Black Pill ROM:
