My little cousin sister was playing with my gf's e65 and somehow she set a lock code, now we cannot turn it back on because it keep asking for the lock code and my cousin sis said she dunno what number she press already. Whenever we wanna unlock the phone, it ask use for a lock code. Try 5 times, then it has to wait 5 minutes... Dang!

Is there any workaround to this problem? Or is my gf's phone forever gone?
