I've made a Backup of my GDFS and that's all. When I finished the flashing I put back my old GDFS in to the phone and EUREKA, yes, my wap data account was there. I hope this information can be useful for you to.

so, dont forget, when you flash your phone always save your GDFS. this is an easy task with setool2lite. you just pres read GDFS and done. it will save a backup of your GDFS in the setool directory in a .bin format. so when you finish the flash of your phone write the old GDFS on your phone to have your old conf.

Note: Some data always be lost like alarms, call list, installed applets (that's what I wanted), etc.

Best Regards. I Will Close This.
