Hi all
Do not update with the latest Facebook app for a 3G phone. I did it today on the phone & it froze after I had downloaded it. I did a hard restart & the phone wouldn't then turn on. I went to the Apple shop in Regents Street & another chap was there & he had the same problem
Apple were fantastic & replaced both phones.
Just seems too much of a coincidence that were both there at the same time for the same reason??
sounds like a once in a lifetime thing and i highly doubt it had to do with FACEBOOK. i'm pretty sure it could have happened with any app
