Hi everyone I have a question, Can you still use the rename song trick to add custom ringtones with firmware 1.1.4? and using itunes 7.6.1?

I have 1.1.2 and Itunes 7.5 and havent updated them because i cant find anywhere if that function was disabled by any of those

Also I would like to know if i use ziphone 2.5t o resstore and go to 1.1.4 to unlock my phone, if i can back upmy old settings smsms contacts etc from my 1.1.2 phone.

Thank you
