I found it online last night and installed it this morning wiping out all my 3rd part applications. It's buggy with the Enterprise Activation...
I have tried to activate my phone 3 times.. wiping it each time after it fails and trying it again... the EA flies through too fast and says it's been activated while BES 4.1.6.26 says the status is "running".. Plus I don't see any of my old emails, or contacts don't sync, nothing else.
:(
I think I will give .210 a try next
