I actually updated my iPhone 3GS on Thursday to the iOS 5.0.1. It's slightly slower, not that bad at all. It functions fine for me. The new software is in the early stages, so performance and battery issues will be resolved eventually. Furthermore, the iOS 5 has solved a major problem I've been having so I'm more than happy now.
iOS5.0.1 has locked my iPhone and does not recognized my sim card (pre-paid plan) anymore plus I cannot use the iPhone at all because it's not activated. Before I was able to use the iPhone other options (iPod, Wi-Fi etc.) when I didn't have a sim card. Now nothing works.
Please help. Thank you
Was your iPhone unlocked (Non-Fido branded) before? That would explain the locking when you updated your iOS firmware. If yes, then you must go get your iPhone unlocked again. Otherwise, updating your iPhone software will not cause you to have to activate your iPhone again unless your completely reset your iPhone. Normally, after a restore or firmware update, you are asked to either 'Restore From Backup' or 'Restore As New'.
It was unlocked before with Fido. After the update it just restored without asking me anything.
I went at Fido today and they told me they cannot unlock it now for iOS 5. They suggested I go buy a turbosim if I wanted to be able to unlocked my phone now. I don't know if I should.
Well it seems there's no turbosim for the iPhone 3GS at the store I went to. They told me that my iPhone is not a Fido phone. They could have unlocked it for me but I would have to downgrade to 4.3.3 or something and I would no longer be able to shut off the phone and always make sure it is charged. Does that mean that everybody that owns an unlocked iPhone cannot upgrade to iOS 5.0.1 without running into these problems? I don't understand this. My phone was bought without a contract and I don't know how it was unlocked in the first place.
Depends what kind of unlock you have: Apple factory-unlock or third party unlock. Apple's unlock is permanently unlocked regardless of the iOS version. The iPhone would have to have been purchased from Apple (not Fido) at full retail. Third party unlocks only apply to a specific software version then if you update your software, it will lock again, and you will have to get it unlocked for that software version. I guess the latest version Fido can unlock is 4.3.3.
