It swaps the whole SFI. It is not possible to swap just the radio as that is just one small facet of the SFI.

sorry to hear your drains, maybe a app is running thats buggy draining your power? i dont know if that would even cause but i would assume one could

Just not comfortable with this release, loosing the camera and the list of applications that won't run have pushed me to hold out for the great mod guys here to worTk their magic.
Thanks to all the people working on theses issues :1244:

Yep, and to give further explanation, by doing so (Swap-A-Radio); you're TECHNICALLY downgrading to an older core OS, and running the Applications from a newer OS. Think of it like this:

Think of it as being similar to downgrading a Windows 7 computer to Windows Vista, and copying the Windows 7 apps (Wordpad, Paint, Calculator, Movie Maker, etc) to your Vista install. You're still running Vista, but benefit from the upgraded version of paint/calculator/etc.
A BlackBerry OS filename is so long because the version numbers apply to different things. The filename:
tells us several things.
1st off is the release number. In .151s case, it is Release 208 of 4.7.0
2nd is the platform (SFI) version. In this case 184.108.40.206
3rd is the Applications version. In this case, 220.127.116.11
It seems that when we talk about BlackBerry OSes, we tend to refer to the Applications version. I am not so sure why, as that is not where the true capabilities of the OS lie. It would technically be more correct to refer to the platform version..... In which case, what we call 18.104.22.168 would be known as 22.214.171.124
To get an idea how swapping the SFI downgrades your OS, use swap-a-radio to switch to an older SFI and see how your platform version drops.
The reason the 5.0 OS is significantly different is the fact that it's on a 4.2.0 platform. This also accounts for the app incompatibilities with 3rd party apps. It's like the difference between Windows Mobile 6.1 and Windows Mobile 6.5 - not everything will be compatible.

I've always wondered myself why that is too.

If you've read the past several pages of threads, the awful truth is that no matter how hard people work on the issues, they are rooted in the SFI file and cannot be fixed. The SFI file is not modular, like the Applications are.

And as far as I know, only RIM themselves have the capacity to sign SFI files.
All of this security is good in a way, though. You can pretty much rest assured that if a leak installs on your device, it's legit.

Perhaps just to avoid going backwards in version numbers in the rare case that a newer app version has a lower platform version (I think that was the case with 126.96.36.199 and 188.8.131.52)

that's the only reason that would make any sense.
