i hope some one can help me

i have a SE 618i and a message pop-up saying memory almost full and i ignored it.

i go to write messages to send sms. when i'm typing it hanged, i cannot turn it off and all the keys are disabled so i quickly remove the battery and wait for 3 minutes and put it back.

now this is the problem

i turn ON my phone and i saw the SE logo and select phone instead of flight. after that it began to reboot and so on. now when i turn it ON, it's pure white on the lcd.

i got to the nearest SE service center but they don't have a software for it coz it was not released locally in the philippines.

thanks
