This is site is excellent. I'm very impressed. There is a wealth of information here. I wasn't able, however, to find the answers I was looking for as of yet, so please help if you can...

I have two Siemens SX56 PDA Phones.
Both have ROM version: A.30.09 ENG.
Both have ROM date of: 01.01.2004
Both have Radio version: A.33.02

I would like to use XDAunlock.
I see that my ROM is too new for it to work. :shock:

Can I safely do the following in this order?
1. Overwrite the ROM with XDA developers Special Edition ROM v1.2
2. Unlock with XDAunlock
3. ReOverwrite the XDA SER v1.2 with the AT&T ROM A.30.09 ENG

Am I missing any steps here?
I will lose all my data and need to backup first right?
My PDA is just a "PC" and all my AT&T account data is on the SIM right?


Thank you for all your help.
