Hello experts

I have Upgraded 3 cydia packges today , Mobile substrate and two more system packages (I can't recall the names but there were a Cydia system packages).

Cydia asked to REEBOT... but it never came back, Now Stuck on Apple Logo loop.
IfunBox wont recognize it in DFU or Recovery.

I found 3 Threads on different Forums that described the exact same problem that i have with the same version in the pase three days.
I'm sure more and more people will announce this problem in the next days. No solution was published anywhere.

Does anyone heared about this problem? there must be some conflict between the ipad 2 4.3.3 and the new Mobilesubstrate Update from saurik.
Please , dont suggest restoring, My Life work is on this device, I can't afford loosing this Data.
I'm strating lossing hope......Please HELP!!

THanks
Dmedalion.
