Is this going to be the best news for those who are on baseband 6.15.00?

MuscleNerd et al had just released resn0w 0.9.6b6 for both Mac and Windows. Here’s the full change logs on their website:
“We’ve released version 0.9.9b6 of redsn0w, with both a functional fix and cosmetic fix for iOS5 jailbreakers. For iPhone 3GS owners with the 06.15 baseband, this redsn0w eliminates the network crash you saw when using Location Services in iOS5 (in fact, you don’t even need to disable Location Services anymore during the initial setup). The cosmetic fix is to the visual countdown you see when going into DFU mode.
It’s okay to re-run this redsn0w over an existing device jailbroken at iOS5. Just choose “Jailbreak” again and de-select Cydia (in other words, all the checkboxes will be unchecked). If you are lucky enough to have an old-bootrom iPhone3GS, please pre-select the IPSW first (redsn0w can’t yet auto-detect the FW version of your old-bootrom 3GS if it’s already been jailbroken).”
One of his followers responded:
“@MuscleNerd by location services do you mean that the gps issue for 3GS users on 6.15 is fixed?”
And he replied:
“the 06.15 BB has “assisted GPS” (aGPS), so it’ll use things like tower triangulation in apps like Google Maps, (and even if aGPS isn’t robust in your area, it’s worth applying this fix so that you can keep Location Services on)”
This doesn’t sound like the GPS is fixed but somehow it improves the functionality of the baseband 6.15.00 on 3G/3GS.
MuscleNerd recommends that you re-apply rehacktivation if you’ve hacktivated with custom iOS created with sn0wbreeze before.
“it gets applied if you’ve hactivated with redsn0w (so worst case: Deactivate with redsn0w, then run redsn0w again to hactivate)”
Have a go and see how much this new redsn0w helps on your Location Services.
