iOS 4.3.3 and problems after jailbreak

Yesterday, the 3 magical jailbreak solutions appeared: redsn0w, Pwnagetool si sn0wbreeze but not everyone is really satisfied after using them. There were users whose Cydia application appeared in Springboard with a white icon after jailbreaking with redsn0w and the problem was that they updated and did not restore to iOS 4.3.3. Others had problems with the lack of signal after updating to iOS 4.3.3 using Pwnagetool, even though they had phones decoded from the factory. Of course, with any jailbreak solution there are problems that manifest themselves differently depending on everyone's iDevice.

So far I haven't had any problems even though I applied the untethered jailbreak over the tethered one. What problems did you have with the jailbreak on iOS 4.3.3?
