Greetings MacRumor community - I am not very well versed in the workings of the iPhone nor IOS, and so I seek your advise. It seems that one day, my gf's phone permanently lost WiFi. She suspects that it occurred after she updated to iOS5. WiFi is grayed out - the phone literally does not see it - (no MAC addr in the phone's About). We've already taken it to the Apple store, and they were willing to provide us a refurbed replacement. Sidestory: Since the phone was on a corporate plan, the replacement phone could not be activated - the Genius almost made my GF walk out of the Apple store with an unactivated phone (I was browsing the Apple store up till that point). The Genius was like - oh, you can take care of it later, but lets wipe your old phone...just hit this button here... Long story short (it gets much longer), I stopped the wiping and requested that we keep the old phone till we get permission from the company for activation. Anyways - I decided that it may be best to see if we can revive it ourselves (since the refurbed looked beatup...) Does anyone have any recommendations on what to do? And can anyone point me to an archive of previous iOS versions? I want to try a fresh iOS4 install to see what happens (instead of just restoring from a backup). Thanks!
