Conform lui notcom, dezvoltatorul aplicatiei TinyUmbrella, se pare ca Apple a introdus o limitare in ceea ce priveste update-ul la iOS 4.2.1. Aceasta limitare afecteaza posesorii de iPhone 4 care incearca sa faca update la iOS 4.2.1 folosind TinyUmbrella si functia sa de update de iOS fara a face update de baseband. Folosind aceasta functie posesorii de iPhone 4 puteau trece de la iOS 4.0/4.0.1/4.0.2 la iOS 4.1 fara a face update de baseband si a mentine posibilitatea de a face decodare. In iOS 4.2.1 Apple a blocat aceasta functie si orice update la iOS 4.2.1 facut cu TinyUmbrella va duce la resetarea telefonului si introducerea acestuia in Recovery Mode de unde NU POATE FI SCOS decat cu restore la iOS 4.1(cat mai merge) sau la iOS 4.2.1.
Deci daca aveti un iPhone 4 NU FOLOSITI TinyUmbrella pentru a face update la iOS 4.2.1 deoarece veti ajunge cu telefonul in Recovery Mode si fara posibilitatea de a il scoate de acolo decat prin restore.
It seems that Apple has decided to put a baseband requirement on iOS. So at this point, if you are using Saurik’s server or tiny umbrella and trying to restore 4.2.1 on an iPhone 4, you will end up in recovery mode and tiny umbrella will not be able to pull you out of recovery. In this case, you will have to restore 4.1 again or you will have to restore 4.2.1 stock and be tether jailbroken. (Of course, I recommend 4.1 and not bothering with 4.2.1 at all). If you are an unlocker, this is a no brainer. Do not update to 4.2.1 even to test it at this point.
