anyone else getting this error??

i know there have been other error codes reported but how about this one? is there a work around? if i hit continue and it wipes my iphone 4, will all my stuff be restored after the update is complete and it is resynced? i'm thinking yes, but i'm not 100% sure.

if anyone successfully got around this issue let me know what you did. i'm currently on ios 4.3.3 jailbroke. at this point in time, i no longer need a jailbreak that's why i'm updating.
